| Throws a TypeError if index arg can not be converted to an Integer |
| 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). |
| |
| ValidateAtomicAccess( typedArray, requestIndex ) |
| |
| 2. Let accessIndex be ? ToIndex(requestIndex). |
| |
| ToIndex ( value ) |
| |
| 2. Else, |
| a. Let integerIndex be ? ToInteger(value). |
| |
| ToInteger(value) |
| |
| 1. Let number be ? ToNumber(argument). |
| |
| Symbol --> Throw a TypeError exception. |
