A null value for bufferData throws a TypeError
|
|
info: |
|
|
Atomics.waitAsync( typedArray, index, value, timeout )
|
|
|
|
1. Return DoWait(async, typedArray, index, value, timeout).
|
|
|
|
DoWait ( mode, typedArray, index, value, timeout )
|
|
|
|
1. Let buffer be ? ValidateSharedIntegerTypedArray(typedArray, true).
|
|
|
|
ValidateSharedIntegerTypedArray ( typedArray [ , waitable ] )
|
|
|
|
2. Perform ? RequireInternalSlot(typedArray, [[TypedArrayName]]).
|
|
|
|
RequireInternalSlot ( O, internalSlot )
|
|
|
|
1. If Type(O) is not Object, throw a TypeError exception.
|
|
2. If O does not have an internalSlot internal slot, throw a TypeError exception.
