Throws a TypeError if value arg is a Symbol

info: |
|
|
Atomics.waitAsync( typedArray, index, value, timeout )
|
|
|
|
1. Return DoWait(async, typedArray, index, value, timeout).
|
|
|
|
DoWait ( mode, typedArray, index, value, timeout )

|
5. Otherwise, let v be ? ToInt32(value).

|
|
ToInt32(value)
|
|
|
|
1.Let number be ? ToNumber(argument).
|
|
|
|
Symbol --> Throw a TypeError exception.
