Returns "not-equal" when value arg does not match an index in the typedArray
info: |
Atomics.waitAsync( typedArray, index, value, timeout )
1. Return DoWait(async, typedArray, index, value, timeout).
DoWait ( mode, typedArray, index, value, timeout )
16. Let w be ! AtomicLoad(typedArray, i).
17. If v is not equal to w, then
a. Perform LeaveCriticalSection(WL).
b. If mode is sync, then
i. Return the String "not-equal".
c. Perform ! Call(capability.[[Resolve]], undefined, « "not-equal" »).
d. Return promiseCapability.[[Promise]].
