description: >
  Returns given initialValue on empty instances without calling callbackfn
info: >
  22.2.3.20 %TypedArray%.prototype.reduce ( callbackfn [ , initialValue ] )

  %TypedArray%.prototype.reduce is a distinct function that implements the same
  algorithm as Array.prototype.reduce as defined in 22.1.3.19 except that the
  this object's [[ArrayLength]] internal slot is accessed in place of performing
  a [[Get]] of "length".

  22.1.3.19 Array.prototype.reduce ( callbackfn [ , initialValue ] )

  ...
  7. Else initialValue is not present,
    ...
    b. Repeat, while kPresent is false and k < len
      ...
      iii. If kPresent is true, then
        1. Let accumulator be ? Get(O, Pk).
      iv. Increase k by 1.
    ...
  8. Repeat, while k < len
    ...
  9. Return accumulator.
