I just noticed that the `Record` constructor does not have a way of getting the keys out of a Record. In fact, as far as I can tell, there is...
`Object.fromEntries` and the `Map` constructor enforce, via [AddEntriesFromIterable](https://tc39.es/ecma262/#sec-add-entries-from-iterable) step 4.d, that the "entry" objects returned by the iterable they take is of Type Object so that you cannot do, for...
These are updates for https://github.com/tc39/ecma262/pull/2819. I made the relevant modification to engine262 in a local branch, ran all of test262, and only found one test whose behavior needed to change,...
https://github.com/tc39/ecma262/pull/2267 changed the sequencing of the `RequireObjectCoercible`-on-base / `ToString`-on-property for member assignments, like `a[b] = c`. Some of the tests for the old behavior were updated, and new tests were...
`const f = 0;` is considered by Prepack to be totally dead. But it's not: the top-level lexical scope is shared across scripts, just below the global scope. So while...
Copying from https://github.com/babel/minify/issues/930#issuecomment-439339599 to make sure it gets tracked: ```js 'use strict'; function foo() { if (bar(), true) { baz(); } else { NOT_REACHABLE(); } } ``` with dead code...
For example, the [docs for `getRoom`](https://matrix-org.github.io/matrix-js-sdk/13.0.0/MemoryStore.html#getRoom) don't link the Room type. If you search for Room the closest you can get is [this page](https://matrix-org.github.io/matrix-js-sdk/13.0.0/module-models_room.html), which does not list any of...
It is almost certainly too early to worry about this, but a couple notes while I'm thinking of them: - The tree grammar specified does not allow `for (var a...
## Introduction [I have an existing issue [here](https://github.com/w3c/webcrypto/issues/265), but I'm hoping to get more eyes on it.] The `SubtleCrypto.deriveKey` API exposes one password-based KDF, `pbkdf2`, which is quite old and...
This implements the change from https://github.com/tc39/ecma262/pull/2812. Test262 PR is at https://github.com/tc39/test262/pull/3631.
