  22.2.3.22 %TypedArray%.prototype.reverse ( )

  %TypedArray%.prototype.reverse is a distinct function that implements the same
  algorithm as Array.prototype.reverse as defined in 22.1.3.21 except that the
  this object's [[ArrayLength]] internal slot is accessed in place of performing
  a [[Get]] of "length".

  22.1.3.21 Array.prototype.reverse ( )

  1. Let O be ? ToObject(this value).
  2. Let len be ? ToLength(? Get(O, "length")).
