Throws a RangeError if value of index arg is out of range
|
|
info: |
|
|
Atomics.waitAsync( typedArray, index, value, timeout )
|
|
|
|
1. Return DoWait(async, typedArray, index, value, timeout).
|
|
|
|
DoWait ( mode, typedArray, index, value, timeout )
|
|
|
|
2. Let i be ? ValidateAtomicAccess(typedArray, index).
|
|
|
|
...
|
|
2.Let accessIndex be ? ToIndex(requestIndex).
|
|
...
|
|
5. If accessIndex ≥ length, throw a RangeError exception.
