  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.
