  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.
