  22.2.3.21 %TypedArray%.prototype.reduceRight ( callbackfn [ , initialValue ] )

  %TypedArray%.prototype.reduceRight is a distinct function that implements the
  same algorithm as Array.prototype.reduceRight as defined in 22.1.3.20 except
  that the this object's [[ArrayLength]] internal slot is accessed in place of
  performing a [[Get]] of "length".

  22.1.3.20 Array.prototype.reduceRight ( callbackfn [ , initialValue ] )

  ...
  8. Repeat, while k ≥ 0
    ...
    c. If kPresent is true, then
      i. Let kValue be ? Get(O, Pk).
      ii. Let accumulator be ? Call(callbackfn, undefined, « accumulator,
      kValue, k, O »).
    d. Decrease k by 1.
