Use a `const` type parameter for `Object.freeze`. by DanielRosenwasser · Pull Request #52317 · microsoft/TypeScript

DanielRosenwasser · 2023-01-19T23:40:37Z

This PR removes an unnecessary signature from Object.freeze by using TypeScript 5.0's new const type parameters.

I think if we want to try this out, 5.0 beta is the right time.

I really want to send a PR which changes the baselines to filter out all line numbers from lib.*.d.ts files; it really sucks to modify a baseline and have it all be line numbers that don't matter.

I was thinking the same - however, maybe start conservative and only do that on related spans.

The other problem is that when you add a new overload to a lib, more than just line numbers change; any use gets more symbols too, so it's not a perfect solution.

That tsserver trace is fixed by ~~#52321~~ #51524.

DanielRosenwasser · 2023-01-20T20:09:32Z

Literally talked myself out of this during today's design meeting. It almost makes sense until you realize that nested objects aren't frozen.

While lots of users would like for Object.freeze to do deep immutability, it doesn't. And while you might want it to be a signal for deep immutability for TypeScript, you can achieve that by doing your own interface merging and adding a new signature to freeze in ObjectConstructor.

DanielRosenwasser added 2 commits January 19, 2023 23:39

Use a const type parameter for Object.freeze.
