description: >
Atomics.waitAsync returns a result object containing a property named "value" whose value is a promise that resolves to "ok" and async is true.

1. Return DoWait(async, typedArray, index, value, timeout).

13. Let promiseCapability be undefined.
14. If mode is async, then
a. Set promiseCapability to ! NewPromiseCapability(%Promise%).
