  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.

  ...
  11. If length is either not present or undefined, then
    ...
  12. Else,
    a. Let newLength be ? ToIndex(length).
