description: >
TypedArray type is validated before `timeout` argument is coerced.
info: |
1. Return DoWait(async, typedArray, index, value, timeout).
DoWait ( mode, typedArray, index, value, timeout )
1. Let buffer be ? ValidateSharedIntegerTypedArray(typedArray, true).
ValidateSharedIntegerTypedArray ( typedArray [ , waitable ] )
1. If waitable is not present, set waitable to false.
2. Perform ? RequireInternalSlot(typedArray, [[TypedArrayName]]).
3. Let typeName be typedArray.[[TypedArrayName]].
4. Let type be the Element Type value in Table 61 for typeName.
5. If waitable is true, then
a. If typeName is not "Int32Array" or "BigInt64Array", throw a TypeError exception.
6. Else,
a. If ! IsUnclampedIntegerElementType(type) is false and ! IsBigIntElementType(type) is false, throw a TypeError exception.
7. Assert: typedArray has a [[ViewedArrayBuffer]] internal slot.
8. Let buffer be typedArray.[[ViewedArrayBuffer]].
9. If IsSharedArrayBuffer(buffer) is false, throw a TypeError exception.
10. Return buffer.
