  22.2.3.13 %TypedArray%.prototype.includes ( searchElement [ , fromIndex ] )

  %TypedArray%.prototype.includes is a distinct function that implements the
  same algorithm as Array.prototype.includes as defined in 22.1.3.11 except that
  the this object's [[ArrayLength]] internal slot is accessed in place of
  performing a [[Get]] of "length".

  22.1.3.11 Array.prototype.includes ( searchElement [ , fromIndex ] )

  ...
  2. Let len be ? ToLength(? Get(O, "length")).
  3. If len is 0, return false.
