Throws a RangeError if bufferByteLength - ToInteger(byteOffset) < 0
info: |
22.2.4.5 TypedArray ( buffer [ , byteOffset [ , length ] ] )
This description applies only if the TypedArray function is called with at
least one argument and the Type of the first argument is Object and that
object has an [[ArrayBufferData]] internal slot.
...
13. If length is undefined, then
a. If bufferByteLength modulo elementSize ≠ 0, throw a RangeError exception.
b. Let newByteLength be bufferByteLength - offset.
c. If newByteLength < 0, throw a RangeError exception.
