  22.2.3.12 %TypedArray%.prototype.forEach ( callbackfn [ , thisArg ] )

  %TypedArray%.prototype.forEach is a distinct function that implements the same
  algorithm as Array.prototype.forEach as defined in 22.1.3.10 except that the
  this object's [[ArrayLength]] internal slot is accessed in place of performing
  a [[Get]] of "length"

  22.1.3.10 Array.prototype.forEach ( callbackfn [ , thisArg ] )

  ...
  4. If thisArg was supplied, let T be thisArg; else let T be undefined.
  ...
  6. Repeat, while k < len
    ...
    c. If kPresent is true, then
      ...
      ii. Perform ? Call(callbackfn, T, « kValue, k, O »).
