  Elements are found in an array-like object

  Array.prototype.lastIndexOf ( searchElement [ , fromIndex ] )

  1. Let O be ? ToObject(this value).
  2. Let len be ? LengthOfArrayLike(O).

  7. Repeat, while k ≥ 0
    a. Let kPresent be ? HasProperty(O, ! ToString(k)).
    b. If kPresent is true, then
      i. Let elementK be ? Get(O, ! ToString(k)).
      ii. Let same be the result of performing Strict Equality Comparison searchElement === elementK.
      iii. If same is true, return k.
