Is it already available in some browsers by default?

[zloirock]

It's generated automatically, so yes, it's available in some environments by default. It's not a browser, it's bun.

But preset-env's shippedProposals does not include bun. Until preset-env recognizes bun as shippedProposals, can we exclude bun here?

I think that it should be solved on the preset-env side, babel/babel#14831.

So, this proposal is supported in Safari 16 that's released today. If you wanna change something in the shippedProposals logic - feel free to do it out of the scope of this PR - I think that the current logic of considering something as "shipped" is incorrect anyway.

@nicolo-ribaudo why I wrote that the way of considering something as "shipped" is incorrect? It's not even the definition of "shipped".

Safari 16 implements the "change array by copy" proposal - all actual methods. However, in the proposal recently was changed the order of errors in %TypedArray%.prototype.with. Because of this minor issue, core-js-compat shows that this method is not supported in Safari 16. With the logic of "shipped proposals" list generation, to this will be added all methods from this proposal with the exception of esnext.typed-array.with.

It should be added too.

@zloirock I'm happy to delegate the decision of what counts as shipped to you: do you know where we can get the "is this supported enough, even if with bugs, to consider it as shipped" data?

[zloirock]

@zloirock at this moment we could only manually support this list.

Note that apparently I forgot to run yarn build when merging this PR; the result is now this: https://github.com/babel/babel-polyfills/blob/main/packages/babel-plugin-polyfill-corejs3/src/shipped-proposals.ts

[zloirock]

Yep, since it's fixed in Safari TP / Bun.
