⏯ Playground Link
💻 Code
const data = new TextEncoder().encode("hello")
// ^? Uint8Array<ArrayBufferLike>
// The `ArrayBufferLike` may include `SharedArrayBuffer`, but `encode()`
// only supports `ArrayBuffer`, so this breaks code expecting an `ArrayBuffer`.
function processData(d: ArrayBuffer) {
// do stuff
}
processData(data.buffer) // This should work, but reported as type error
🙁 Actual behavior
Values returned by TextEncoder.encode are not assignable to ArrayBuffer.
🙂 Expected behavior
Values returned by TextEncoder.encode should be assignable to ArrayBuffer.
