Current Status: You'd have to check the TC39 proposals repository or the official proposal text for the most recent status. As of my last update, it had not yet reached Stage 4 (final stage) of the TC39 process, which means it wasn't part of the ECMAScript specification yet.
Project mention: Union, intersection, difference, and more are coming to JavaScript Sets | news.ycombinator.com | 2024-02-19relevant issue, which is at the crux of this problem: https://github.com/tc39/proposal-record-tuple/issues/387
Indeed. These may be even more important...

Global iterator type is coming: https://github.com/tc39/proposal-iterator-helpers
But a method named `groupBy` on iterators traditionally means a different thing: https://github.com/tc39/proposal-array-grouping/issues/51#is...
Global iterable type it's too late for, since there's many extant iterables in the language and on the web which don't have it in their prototype chain and can't reasonably be changed.
The new change array by copy methods (ES2023) will also work with tuples. So while you can't
target - Specifies the ECMAScript target version for the emitted JavaScript. Defaults to ES3. To ensure maximum compatibility, set this to the lowest version that your code requires to run. ESNext setting allows you to target the latest supported proposed features.
You can check why Mozilla and Apple have opted to not support this.
https://github.com/mozilla/standards-positions/issues/154
https://github.com/WebKit/standards-positions/issues/28
Neither Mozilla or Webkit are satisfied that the proposal is safe by default, and contains footguns for the user that can be pretty destructive.
We will soon support WASM imports (`import source foo from "./foo.wasm"`). [1]
