Types for ArrayBuffer.transfer and ArrayBuffer.transferToFixedLength are missing.

[BlackAsLight]

Version: Deno 2.0.4

According to MDN docs, Deno supports both .transfer() and .transferToFixedLength() while Node doesn't, and this is true when running the code, but the TypeScript linting doesn't display these options. Saying it doesn't exist.

TypeScript 5.7 will include ES2024 type definitions. Please wait a moment.

Looks like a duplicate of #25993

[BlackAsLight]

Is there a scheduled date for when 5.7 will be released?

[petamoriken]

It will be released on 2024-11-21.
microsoft/TypeScript#59905

Oh this is gonna be a tight one, we are scheduled to release on Nov, 21st too. Maybe we'll delay by one day to include TS upgrade.

NOTE:

TypeScript 5.7 will bring a breaking change that will make TypedArrays generic.

In ECMAScript 2024, SharedArrayBuffer and ArrayBuffer have types that slightly diverge. To bridge the gap and preserve the underlying buffer type, all TypedArrays (like Uint8Array and others) are now also generic.

interface Uint8Array<TArrayBuffer extends ArrayBufferLike = ArrayBufferLike> {
    // ...
}

Type definition files will need to be updated and @types/node will need to be pinned to v22.7.4 or later.
