💻 Code
const array = new Uint8Array(await Promise.resolve().then(() => new ArrayBuffer(10)))🙁 Actual behavior
The above code throws the following error when passing to a TypedArray an awaited ArrayBuffer from a Promise involving a then call
No overload matches this call.
The last overload gave the following error.
Argument of type 'Iterable<number> | ArrayBuffer' is not assignable to parameter of type 'ArrayBuffer'.
Type 'Iterable<number>' is missing the following properties from type 'ArrayBuffer': byteLength, slice, [Symbol.toStringTag]
🙂 Expected behavior
The code should work because the following will not throw an error as the follow examples don't throw an error (also in playground link):
// refactoring the arrayBuffer definition to a separate variable doesn't throw an error
const arrayBuffer = await Promise.resolve().then(() => new ArrayBuffer(10))
const array = new Uint8Array(arrayBuffer)// without the "then" it doesn't throw an error
const array = new Uint8Array(Promise.resolve(new ArrayBuffer(10)))
