description: >
The `length` parameter is converted to a value numeric index value.
info: |
ArrayBuffer( length )
1. If NewTarget is undefined, throw a TypeError exception.
2. Let byteLength be ? ToIndex(length).
3. Return ? AllocateArrayBuffer(NewTarget, byteLength).
ToIndex( value )
1. If value is undefined, then
a. Let index be 0.
2. Else,
a. Let integerIndex be ? ToInteger(value).
b. If integerIndex < 0, throw a RangeError exception.
c. Let index be ! ToLength(integerIndex).
d. If SameValueZero(integerIndex, index) is false, throw a RangeError exception.
3. Return index.
