 ## Trying Out React
 
 If you're just interested in playing around with React, you can use CodePen. Try starting from [this Hello World example code](http://codepen.io/gaearon/pen/rrpgNB?editors=0010). You don't need to install anything; you can just modify the code and see if it works.
 
 If you prefer to use your own text editor, you can also <a href="/react/downloads/single-file-example.html" download="hello.html">download this HTML file</a>, edit it, and open it from the local filesystem in your browser. It does a slow runtime code transformation, so don't use it in production.
 
-## Creating a Single Page Application
+If you want to use it for a full application, there are two popular ways to get started with React: using Create React App, or adding it to an existing application.
+
+<block id="newapptab" role="tabpanel" class="newapp" />
+
+## Creating a New Application
 
 [Create React App](http://github.com/facebookincubator/create-react-app) is the best way to start building a new React single page application. It sets up your development environment so that you can use the latest JavaScript features, provides a nice developer experience, and optimizes your app for production.
 
 ```bash
 npm install -g create-react-app
-create-react-app hello-world
-cd hello-world
+create-react-app my-app
+
+cd my-app
 npm start
 ```
 
-Create React App doesn't handle backend logic or databases; it just creates a frontend build pipeline, so you can use it with any backend you want. It uses [webpack](https://webpack.js.org/), [Babel](http://babeljs.io/) and [ESLint](http://eslint.org/) under the hood, but configures them for you.
+Create React App doesn't handle backend logic or databases; it just creates a frontend build pipeline, so you can use it with any backend you want. It uses build tools like Babel and webpack under the hood, but works with zero configuration.
+
+When you're ready to deploy to production, running `npm run build` will create an optimized build of your app in the `build` folder. You can learn more about Create React App [from its README](https://github.com/facebookincubator/create-react-app#create-react-app-) and the [User Guide](https://github.com/facebookincubator/create-react-app/blob/master/packages/react-scripts/template/README.md#table-of-contents).

+React can be used in any web application. It can be embedded in other applications and, with a little care, other applications can be embedded in React. This guide will examine some of the more common use cases, focusing on integration with [jQuery](https://jquery.com/) and [Backbone](http://backbonejs.org/), but the same ideas can be applied to integrating components with any existing code.
+
+## Integrating with DOM Manipulation Plugins
+
+React is unaware of changes made to the DOM outside of React. It determines updates based on its own internal representation, and if the same DOM nodes are manipulated by another library, React gets confused and has no way to recover.
+
+This does not mean it is impossible or even necessarily difficult to combine React with other ways of affecting the DOM, you just have to be mindful of what each are doing.
+
+The easiest way to avoid conflicts is to prevent the React component from updating. You can do this by rendering elements that React has no reason to update, like an empty `<div />`.
+
+### How to Approach the Problem
+
+To demonstrate this, let's sketch out a wrapper for a generic jQuery plugin.
+
+We will attach a [ref](/react/docs/refs-and-the-dom.html) to the root DOM element. Inside `componentDidMount`, we will get a reference to it so we can pass it to the jQuery plugin.
+
+To prevent React from touching the DOM after mounting, we will return an empty `<div />` from the `render()` method. The `<div />` element has no properties or children, so React has no reason to update it, leaving the jQuery plugin free to manage that part of the DOM:
+
+```js{3,4,8,12}
+class SomePlugin extends React.Component {
+  componentDidMount() {
+    this.$el = $(this.el);
+    this.$el.somePlugin();
+  }
+
+  componentWillUnmount() {
+    this.$el.somePlugin('destroy');
+  }
+
+  render() {
+    return <div ref={el => this.el = el} />;
+  }
+}
+```
+
+Note that we defined both `componentDidMount` and `componentWillUnmount` [lifecycle hooks](/react/docs/react-component.html#the-component-lifecycle). Many jQuery plugins attach event listeners to the DOM so it's important to detach them in `componentWillUnmount`. If the plugin does not provide a method for cleanup, you will probably have to provide your own, remembering to remove any event listeners the plugin registered to prevent memory leaks.
+
+### Integrating with jQuery Chosen Plugin
+
+For a more concrete example of these concepts, let's write a minimal wrapper for the plugin [Chosen](https://harvesthq.github.io/chosen/), which augments `<select>` inputs.
+
+>**Note:**
+>
+>Just because it's possible, doesn't mean that it's the best approach for React apps. We encourage you to use React components when you can. React components are easier to reuse in React applications, and often provide more control over their behavior and appearance.
+
+First, let's look at what Chosen does to the DOM.
+
+If you call it on a `<select>` DOM node, it reads the attributes off of the original DOM node, hides it with an inline style, and then appends a separate DOM node with its own visual representation right after the `<select>`. Then it fires jQuery events to notify us about the changes.
+
+Let's say that this is the API we're striving for with our `<Chosen>` wrapper React component:
+
+```js
+function Example() {
+  return (
+    <Chosen onChange={value => console.log(value)}>
+      <option>vanilla</option>
+      <option>chocolate</option>
+      <option>strawberry</option>
+    </Chosen>
+  );
+}
+```
+
+We will implement it as an [uncontrolled component](/react/docs/uncontrolled-components.html) for simplicity.
+
+First, we will create an empty component with a `render()` method where we return `<select>` wrapped in a `<div>`:
+
+```js{4,5}
+class Chosen extends React.Component {
+  render() {
+    return (
+      <div>
+        <select className="Chosen-select" ref={el => this.el = el}>
+          {this.props.children}
+        </select>
+      </div>
+    );
+  }
+}
+```
+
+Notice how we wrapped `<select>` in an extra `<div>`. This is necessary because Chosen will append another DOM element right after the `<select>` node we passed to it. However, as far as React is concerned, `<div>` always only has a single child. This is how we ensure that React updates won't conflict with the extra DOM node appended by Chosen. It is important that if you modify the DOM outside of React flow, you must ensure React doesn't have a reason to touch those DOM nodes.
+
+Next, we will implement the lifecycle hooks. We need to initialize Chosen with the ref to the `<select>` node in `componentDidMount`, and tear it down in `componentWillUnmount`:
+
+```js{2,3,7}
+componentDidMount() {
+  this.$el = $(this.el);
+  this.$el.chosen();
+}
+
+componentWillUnmount() {
+  this.$el.chosen('destroy');
+}
+```
+
+[Try it on CodePen.](http://codepen.io/gaearon/pen/qmqeQx?editors=0010)
+
+Note that React assigns no special meaning to the `this.el` field. It only works because we have previously assigned this field from a `ref` in the `render()` method:
+
+```js
+<select className="Chosen-select" ref={el => this.el = el}>
+```
+
+This is enough to get our component to render, but we also want to be notified about the value changes. To do this, we will subscribe to the jQuery `change` event on the `<select>` managed by Chosen.
+
+We won't pass `this.props.onChange` directly to Chosen because component's props might change over time, and that includes event handlers. Instead, we will declare a `handleChange()` method that calls `this.props.onChange`, and subscribe it to the jQuery `change` event:
+
+```js{5,6,10,14-16}
+componentDidMount() {
+  this.$el = $(this.el);
+  this.$el.chosen();
+
+  this.handleChange = this.handleChange.bind(this);
+  this.$el.on('change', this.handleChange);
+}
+
+componentWillUnmount() {
+  this.$el.off('change', this.handleChange);
+  this.$el.chosen('destroy');
+}
+
+handleChange(e) {
+  this.props.onChange(e.target.value);
+}
+```
+
+[Try it on CodePen.](http://codepen.io/gaearon/pen/bWgbeE?editors=0010)
+
+Finally, there is one more thing left to do. In React, props can change over time. For example, the `<Chosen>` component can get different children if parent component's state changes. This means that at integration points it is important that we manually update the DOM in response to prop updates, since we no longer let React manage the DOM for us.
+
+Chosen's documentation suggests that we can use jQuery `trigger()` API to notify it about changes to the original DOM element. We will let React take care of updating `this.props.children` inside `<select>`, but we will also add a `componentDidUpdate()` lifecycle hook that notifies Chosen about changes in the children list:
+
+```js{2,3}
+componentDidUpdate(prevProps) {
+  if (prevProps.children !== this.props.children) {
+    this.$el.trigger("chosen:updated");
+  }
+}
+```
+
+This way, Chosen will know to update its DOM element when the `<select>` children managed by React change.
+
+The complete implementation of the `Chosen` component looks like this:
+
+```js
+class Chosen extends React.Component {
+  componentDidMount() {
+    this.$el = $(this.el);
+    this.$el.chosen();
+
+    this.handleChange = this.handleChange.bind(this);
+    this.$el.on('change', this.handleChange);
+  }
+  
+  componentDidUpdate(prevProps) {
+    if (prevProps.children !== this.props.children) {
+      this.$el.trigger("chosen:updated");
+    }
+  }
+
+  componentWillUnmount() {
+    this.$el.off('change', this.handleChange);
+    this.$el.chosen('destroy');
+  }
+  
+  handleChange(e) {
+    this.props.onChange(e.target.value);
+  }
+
+  render() {
+    return (
+      <div>
+        <select className="Chosen-select" ref={el => this.el = el}>
+          {this.props.children}
+        </select>
+      </div>
+    );
+  }
+}
+```

+
+## Integrating with Other View Libraries
+
+React can be embedded into other applications thanks to the flexibility of [`ReactDOM.render()`](/react/docs/react-dom.html#render).
+
+Although React is commonly used at startup to load a single root React component into the DOM, `ReactDOM.render()` can also be called multiple times for independent parts of the UI which can be as small as a button, or as large as an app.
+
+In fact, this is exactly how React is used at Facebook. This lets us write applications in React piece by piece, and combine it with our existing server-generated templates and other client-side code.
+
+### Replacing String-Based Rendering with React
+
+A common pattern in older web applications is to describe chunks of the DOM as a string and insert it into the DOM like so: `$el.html(htmlString)`. These points in a codebase are perfect for introducing React. Just rewrite the string based rendering as a React component.
+
+So the following jQuery implementation...
+
+```js
+$('#container').html('<button id="btn">Say Hello</button>');
+$('#btn').click(function() {
+  alert('Hello!');
+});
+```
+
+...could be rewritten using a React component:
+
+```js
+function Button() {
+  return <button id="btn">Say Hello</button>;
+}
+
+ReactDOM.render(
+  <Button />,
+  document.getElementById('container'),
+  function() {
+    $('#btn').click(function() {
+      alert('Hello!');
+    });
+  }
+);
+```
+
+From here you could start moving more logic into the component and begin adopting more common React practices. For example, in components it is best not to rely on IDs because the same component can be rendered multiple times. Instead, we will use the [React event system](/react/docs/handling-events.html) and register the click handler directly on the React `<button>` element:
+
+```js{2,6,9}
+function Button(props) {
+  return <button onClick={props.onClick}>Say Hello</button>;
+}
+
+function HelloButton() {
+  function handleClick() {
+    alert('Hello!');
+  }
+  return <Button onClick={handleClick} />;
+}
+
+ReactDOM.render(
+  <HelloButton />,
+  document.getElementById('container')
+);
+```
+
+[Try it on CodePen.](http://codepen.io/gaearon/pen/RVKbvW?editors=1010)
+
+You can have as many such isolated components as you like, and use `ReactDOM.render()` to render them to different DOM containers. Gradually, as you convert more of your app to React, you will be able to combine them into larger components, and move some of the `ReactDOM.render()` calls up the hierarchy.
+
+### Embedding React in a Backbone View
+
+[Backbone](http://backbonejs.org/) views typically use HTML strings, or string-producing template functions, to create the content for their DOM elements. This process, too, can be replaced with rendering a React component.
+
+Below, we will create a Backbone view called `ParagraphView`. It will override Backbone's `render()` function to render a React `<Paragraph>` component into the DOM element provided by Backbone (`this.el`). Here, too, we are using [`ReactDOM.render()`](/react/docs/react-dom.html#render):
+
+```js{1,5,8,12}
+function Paragraph(props) {
+  return <p>{props.text}</p>;
+}
+
+const ParagraphView = Backbone.View.extend({
+  render() {
+    const text = this.model.get('text');
+    ReactDOM.render(<Paragraph text={text} />, this.el);
+    return this;
+  },
+  remove() {
+    ReactDOM.unmountComponentAtNode(this.el);
+    Backbone.View.prototype.remove.call(this);
+  }
+});
+```
+
+[Try it on CodePen.](http://codepen.io/gaearon/pen/gWgOYL?editors=0010)
+
+It is important that we also call `ReactDOM.unmountComponentAtNode()` in the `remove` method so that React unregisters event handlers and other resources associated with the component tree when it is detached.
+
+When a component is removed *from within* a React tree, the cleanup is performed automatically, but because we are removing the entire tree by hand, we must call it this method.
+
+## Integrating with Model Layers
+
+While it is generally recommended to use unidirectional data flow such as [React state](/react/docs/lifting-state-up.html), [Flux](http://facebook.github.io/flux/), or [Redux](http://redux.js.org/), React components can use a model layer from other frameworks and libraries.
+
+### Using Backbone Models in React Components
+
+The simplest way to consume [Backbone](http://backbonejs.org/) models and collections from a React component is to listen to the various change events and manually force an update.
+
+Components responsible for rendering models would listen to `'change'` events, while components responsible for rendering collections would listen for `'add'` and `'remove'` events. In both cases, call [`this.forceUpdate()`](/react/docs/react-component.html#forceupdate) to rerender the component with the new data.
+
+In the example below, the `List` component renders a Backbone collection, using the `Item` component to render individual items.
+
+```js{1,7-9,12,16,24,30-32,35,39,46}
+class Item extends React.Component {
+  constructor(props) {
+    super(props);
+    this.handleChange = this.handleChange.bind(this);
+  }
+
+  handleChange() {
+    this.forceUpdate();
+  }
+
+  componentDidMount() {
+    this.props.model.on('change', this.handleChange);
+  }
+
+  componentWillUnmount() {
+    this.props.model.off('change', this.handleChange);
+  }
+
+  render() {
+    return <li>{this.props.model.get('text')}</li>;
+  }
+}
+
+class List extends React.Component {
+  constructor(props) {
+    super(props);
+    this.handleChange = this.handleChange();
+  }
+
+  handleChange() {
+    this.forceUpdate();
+  }
+
+  componentDidMount() {
+    this.props.collection.on('add', 'remove', this.handleChange);
+  }
+
+  componentWillUnmount() {
+    this.props.collection.off('add', 'remove', this.handleChange);
+  }
+
+  render() {
+    return (
+      <ul>
+        {this.props.collection.map(model => (
+          <Item key={model.cid} model={model} />
+        ))}
+      </ul>
+    );
+  }
+}
+```
+

+
+### Extracting Data from Backbone Models
+
+The approach above requires your React components to be aware of the Backbone models and collections. If you later plan to migrate to another data management solution, you might want to concentrate the knowledge about Backbone in as few parts of the code as possible.
+
+One solution to this is to extract the model's attributes as plain data whenever it changes, and keep this logic in a single place. The following is [a higher-order component](/react/docs/higher-order-components.html) that extracts all attributes of a Backbone model into state, passing the data to the wrapped component.
+
+This way, only the higher-order component needs to know about Backbone model internals, and most components in the app can stay agnostic of Backbone.
+
+In the example below, we will make a copy of the model's attributes to form the initial state. We subscribe to the `change` event (and unsubscribe on unmounting), and when it happens, we update the state with the model's current attributes. Finally, we make sure that if the `model` prop itself changes, we don't forget to unsubscribe from the old model, and subscribe to the new one.
+
+Note that this example is not meant to be exhaustive with regards to working with Backbone, but it should give you an idea for how to approach this in a generic way:
+
+```js{1,5,10,14,16,17,22,26,32}
+function connectToBackboneModel(WrappedComponent) {
+  return class BackboneComponent extends React.Component {
+    constructor(props) {
+      super(props);
+      this.state = Object.assign({}, props.model.attributes);
+      this.handleChange = this.handleChange.bind(this);
+    }
+
+    componentDidMount() {
+      this.props.model.on('change', this.handleChange);
+    }
+
+    componentWillReceiveProps(nextProps) {
+      this.setState(Object.assign({}, nextProps.model.attributes));
+      if (nextProps.model !== this.props.model) {
+        this.props.model.off('change', this.handleChange);
+        nextProps.model.on('change', this.handleChange);
+      }
+    }
+
+    componentWillUnmount() {
+      this.props.model.off('change', this.handleChange);
+    }
+
+    handleChange(model) {
+      this.setState(model.changedAttributes());
+    }
+
+    render() {
+      const propsExceptModel = Object.assign({}, this.props);
+      delete propsExceptModel.model;
+      return <WrappedComponent {...propsExceptModel} {...this.state} />;
+    }
+  }
+}
+```
+
+To demonstrate how to use it, we will connect a `NameInput` React component to a Backbone model, and update its `firstName` attribute every time the input changes:
+
+```js{4,6,11,15,19-21}
+function NameInput(props) {
+  return (
+    <p>
+      <input value={props.firstName} onChange={props.handleChange} />
+      <br />
+      My name is {props.firstName}.
+    </p>
+  );
+}
+
+const BackboneNameInput = connectToBackboneModel(NameInput);
+
+function Example(props) {
+  function handleChange(e) {
+    model.set('firstName', e.target.value);
+  }
+
+  return (
+    <BackboneNameInput
+      model={props.model}
+      handleChange={handleChange}
+    />
+  );
+}
+
+const model = new Backbone.Model({ firstName: 'Frodo' });
+ReactDOM.render(
+  <Example model={model} />,
+  document.getElementById('root')
+);
+```
+
+[Try it on CodePen.](http://codepen.io/gaearon/pen/PmWwwa?editors=0010)
+
+This technique is not limited to Backbone. You can use React with any model library by subscribing to its changes in the lifecycle hooks and, optionally, copying the data into the local React state.

+`setState()` enqueues changes to the component state and tells React that this component and its children need to be re-rendered with the updated state. This is the primary method you use to update the user interface in response to event handlers and server responses.
 
-The first argument can be an object (containing zero or more keys to update) or a function (of state and props) that returns an object containing keys to update.

-Here is the simple object usage:
+`setState()` does not always immediately update the component. It may batch or defer the update until later. This makes reading `this.state` right after calling `setState()` a potential pitfall. Instead, use `componentDidUpdate` or a `setState` callback (`setState(updater, callback)`), either of which are guaranteed to fire after the update has been applied. If you need to set the state based on the previous state, read about the `updater` argument below.
+
+`setState()` will always lead to a re-render unless `shouldComponentUpdate()` returns `false`. If mutable objects are being used and conditional rendering logic cannot be implemented in `shouldComponentUpdate()`, calling `setState()` only when the new state differs from the previous state will avoid unnecessary re-renders.
+
+The first argument is an `updater` function with the signature:
 
 ```javascript
-this.setState({mykey: 'my new value'});
+(prevState, props) => nextState
 ```
 
-It's also possible to pass a function with the signature `function(state, props) => newState`. This enqueues an atomic update that consults the previous value of state and props before setting any values. For instance, suppose we wanted to increment a value in state by `props.step`:
+`prevState` is a reference to the previous state. It should not be directly mutated. Instead, changes should be represented by building a new state object based on the input from `prevState` and `props`. For instance, suppose we wanted to increment a value in state by `props.step`:
 
 ```javascript
 this.setState((prevState, props) => {
-  return {myInteger: prevState.myInteger + props.step};
+  return {counter: prevState.counter + props.step};
 });
 ```
 
-The second parameter is an optional callback function that will be executed once `setState` is completed and the component is re-rendered. Generally we recommend using `componentDidUpdate()` for such logic instead.
+Both `prevState` and `props` received by the updater function are guaranteed to be up-to-date.
 
-`setState()` does not immediately mutate `this.state` but creates a pending state transition. Accessing `this.state` after calling this method can potentially return the existing value.
+The second parameter to `setState()` is an optional callback function that will be executed once `setState` is completed and the component is re-rendered. Generally we recommend using `componentDidUpdate()` for such logic instead.
 
-There is no guarantee of synchronous operation of calls to `setState` and calls may be batched for performance gains.
+You may optionally pass an object as the first argument to `setState()` instead of a function:
 
-`setState()` will always lead to a re-render unless `shouldComponentUpdate()` returns `false`. If mutable objects are being used and conditional rendering logic cannot be implemented in `shouldComponentUpdate()`, calling `setState()` only when the new state differs from the previous state will avoid unnecessary re-renders.
+```javascript
+setState(stateChange, [callback])
+```
+
+This performs a shallow merge of `stateChange` into the new state, e.g., to adjust a shopping cart item quantity:
+
+```javascript
+this.setState({quantity: 2})
+```
+
+This form of `setState()` is also asynchronous, and multiple calls during the same cycle may be batched together. For example, if you attempt to increment an item quantity more than once in the same cycle, that will result in the equivalent of:
+
+```javaScript
+Object.assign(
+  previousState,
+  {quantity: state.quantity + 1},
+  {quantity: state.quantity + 1},
+  ...
+)
+```
+
+Subsequent calls will override values from previous calls in the same cycle, so the quantity will only be incremented once. If the next state depends on the previous state, we recommend using the updater function form, instead:
+
+```js
+this.setState((prevState) => {
+  return {counter: prevState.quantity + 1};
+});
+```
+

-Your first inclination may be to use refs to "make things happen" in your app. If this is the case, take a moment and think more critically about where state should be owned in the component hierarchy. Often, it becomes clear that the proper place to "own" that state is at a higher level in the hierarchy. See the [Lifting State Up](/react/docs/lifting-state-up.html) guide for examples of this.
+In rare cases, you might want to have access to a child's DOM node from a parent component. This is generally not recommended because it breaks component encapsulation, but it can occasionally be useful for triggering focus or measuring the size or position of a child DOM node.
+
+While you could [add a ref to to the child component](#adding-a-ref-to-a-class-component), this is not an ideal solution, as you would only get a component instance rather than a DOM node. Additionally, this wouldn't work with functional components.
+
+Instead, in such cases we recommend exposing a special prop on the child. The child would take a function prop with an arbitrary name (e.g. `inputRef`) and attach it to the DOM node as a `ref` attribute. This lets the parent pass its ref callback to the child's DOM node through the component in the middle.
+
+This works both for classes and for functional components.
+
+```javascript{4,13}
+function CustomTextInput(props) {
+  return (
+    <div>
+      <input ref={props.inputRef} />
+    </div>
+  );
+}
+
+class Parent extends React.Component {
+  render() {
+    return (
+      <CustomTextInput
+        inputRef={el => this.inputElement = el}
+      />
+    );
+  }
+}
+```
+
+In the example above, `Parent` passes its ref callback as an `inputRef` prop to the `CustomTextInput`, and the `CustomTextInput` passes the same function as a special `ref` attribute to the `<input>`. As a result, `this.inputElement` in `Parent` will be set to the DOM node corresponding to the `<input>` element in the `CustomTextInput`.
+
+Note that the name of the `inputRef` prop in the above example has no special meaning, as it is a regular component prop. However, using the `ref` attribute on the `<input>` itself is important, as it tells React to attach a ref to its DOM node.
+
+This works even though `CustomTextInput` is a functional component. Unlike the special `ref` attribute which can [only be specified for DOM elements and for class components](#refs-and-functional-components), there are no restrictions on regular component props like `inputRef`.
+
+Another benefit of this pattern is that it works several components deep. For example, imagine `Parent` didn't need that DOM node, but a component that rendered `Parent` (let's call it `Grandparent`) needed access to it. Then we could let the `Grandparent` specify the `inputRef` prop to the `Parent`, and let `Parent` "forward" it to the `CustomTextInput`:
+
+```javascript{4,12,22}
+function CustomTextInput(props) {
+  return (
+    <div>
+      <input ref={props.inputRef} />
+    </div>
+  );
+}
+
+function Parent(props) {
+  return (
+    <div>
+      My input: <CustomTextInput inputRef={props.inputRef} />
+    </div>
+  );
+}
+
+
+class Grandparent extends React.Component {
+  render() {
+    return (
+      <Parent
+        inputRef={el => this.inputElement = el}
+      />
+    );
+  }
+}
+```
+
+Here, the ref callback is first specified by `Grandparent`. It is passed to the `Parent` as a regular prop called `inputRef`, and the `Parent` passes it to the `CustomTextInput` as a prop too. Finally, the `CustomTextInput` reads the `inputRef` prop and attaches the passed function as a `ref` attribute to the `<input>`. As a result, `this.inputElement` in `Grandparent` will be set to the DOM node corresponding to the `<input>` element in the `CustomTextInput`.
+
+All things considered, we advise against exposing DOM nodes whenever possible, but this can be a useful escape hatch. Note that this approach requires you to add some code to the child component. If you have absolutely no control over the child component implementation, your last option is to use [`findDOMNode()`](/react/docs/react-dom.html#finddomnode), but it is discouraged.

-/**
- * Summary of `ReactBrowserEventEmitter` event handling:
- *
- *  - Top-level delegation is used to trap most native browser events. This
- *    may only occur in the main thread and is the responsibility of
- *    ReactEventListener, which is injected and can therefore support pluggable
- *    event sources. This is the only work that occurs in the main thread.
- *
- *  - We normalize and de-duplicate events to account for browser quirks. This
- *    may be done in the worker thread.
- *
- *  - Forward these native events (with the associated top-level type used to
- *    trap it) to `EventPluginHub`, which in turn will ask plugins if they want
- *    to extract any synthetic events.
- *
- *  - The `EventPluginHub` will then process each event by annotating them with
- *    "dispatches", a sequence of listeners and IDs that care about that event.
- *
- *  - The `EventPluginHub` then dispatches the events.

You can also click on a link in the move list to go "back in time" and see what the board looked like just after that move was made.
+
+### Prerequisites
+
+We'll assume some familiarity with HTML and JavaScript but you should be able to follow along even if you haven't used them before.
+
+If you need a refresher on JavaScript, we recommend reading [this guide](https://developer.mozilla.org/en-US/docs/Web/JavaScript/A_re-introduction_to_JavaScript). Note that we're also using some features from ES6, a recent version of JavaScript. In this tutorial, we're using [arrow functions](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions), [classes](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes), [`let`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/let), and [`const`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/const) statements. You can use <a href="http://babeljs.io/repl/#?babili=false&evaluate=true&lineWrap=false&presets=es2015%2Creact&experimental=false&loose=false&spec=false&code=const%20element%20%3D%20%3Ch1%3EHello%2C%20world!%3C%2Fh1%3E%3B%0Aconst%20container%20%3D%20document.getElementById('root')%3B%0AReactDOM.render(element%2C%20container)%3B%0A">Babel REPL</a> to check what ES6 code compiles to.
+
+### How to Follow Along
+
+#### Following Along in Browser
+
+We'll be using an online editor called CodePen in this guide. You can begin by opening this <a href="https://codepen.io/gaearon/pen/JNYBEZ?editors=0010" target="_blank">starter code</a>. It should display an empty tic-tac-toe field. We will be editing that code during this tutorial.
+
+#### Following Along Locally
+
+You can also follow along locally if you don't mind a few extra steps:
+
+1. Make sure you have a recent version of [Node.js](https://nodejs.org/en/) installed.
+2. Follow the [installation instructions](/react/docs/installation.html#creating-a-new-application) to create a new project.
+3. Delete all files in the `src/` folder of the new project.
+4. Add a file named `index.css` in the `src/` folder with <a href="https://codepen.io/gaearon/pen/JNYBEZ?editors=0100" target="_blank">this CSS code</a>.
+5. Add a file named `index.js` in the `src/` folder with <a href="https://codepen.io/gaearon/pen/JNYBEZ?editors=0010" target="_blank">this JS code</a>, and then add three lines to the top of it:
+
+    ```js
+    import React from 'react';
+    import ReactDOM from 'react-dom';
+    import './index.css';
+    ```
+
+Now if you run `npm start` in the project folder and open `http://localhost:3000` in the browser, you should see an empty tic-tac-toe field.
+
+### Help, I'm Stuck!
+
+If you get stuck, check out the [community support resources](https://facebook.github.io/react/community/support.html). In particular, [Reactiflux chat](/react/community/support.html#reactiflux-chat) is a great way to get quick help. If you don't get a good answer anywhere, please file an issue, and we'll help you out.
+
+You can also look at the <a href="https://codepen.io/gaearon/pen/VbvBWg?editors=0010" target="_blank">final version of the code</a>.

-  React.createElement('ul', ...)
+  React.createElement('h1', /* ... h1 children ... */),
+  React.createElement('ul', /* ... ul children ... */)
 );
 ```
 
+If you're curious, `createElement()` is described in more detail in the [API reference](/react/docs/react-api.html#createelement), but we won't be using it directly in this tutorial. Instead, we will keep using JSX.
+
 You can put any JavaScript expression within braces inside JSX. Each React element is a real JavaScript object that you can store in a variable or pass around your program.
 
 The `ShoppingList` component only renders built-in DOM components, but you can compose custom React components just as easily, by writing `<ShoppingList />`. Each component is encapsulated so it can operate independently, which allows you to build complex UIs out of simple components.

+1. The `onClick` prop on the built-in DOM `<button>` component tells React to set up a click event listener.
+2. When the button is clicked, React will call the `onClick` event handler defined in Square's `render()` method.
+3. This event handler calls `this.props.onClick()`. Square's props were specified by the Board.
+4. This is how we get into `onClick` passed from the Board, which runs `this.handleClick()` on the Board.
+5. We have not defined `this.handleClick` on the Board yet, so the code crashes.
+
+Note that `onClick` on the DOM `<button>` component has a special meaning to React, but we could have called `onClick` prop in Square and `handleClick` in Board something else. It is, however, a common convention in React apps to use `on*` names for the handler prop names and `handle*` for their implementations.

 Determining how an immutable object has changed is considerably easier. If the object being referenced is different from before, then the object has changed. That's it.

+#### Determining When To Re-render in React
 
 The biggest benefit of immutability in React comes when you build simple _pure components_. Since immutable data can more easily determine if changes have been made it also helps to determine when a component requires being re-rendered.
 
 To learn how you can build *pure components* take a look at [shouldComponentUpdate()](https://facebook.github.io/react/docs/update.html). Also, take a look at the [Immutable.js](https://facebook.github.io/immutable-js/) library to strictly enforce immutable data.

 Back to our project, you can now delete the `constructor` from `Square`; we won't need it any more. In fact, React supports a simpler syntax called **stateless functional components** for component types like Square that only consist of a `render` method. Rather than define a class extending React.Component, simply write a function that takes props and returns what should be rendered:
