  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.

  ...
  14. Else,
    a. Let newLength be ? ToLength(length).
    b. Let newByteLength be newLength × elementSize.
    c. If offset+newByteLength > bufferByteLength, throw a RangeError exception.
