  Array.prototype.findLast ( predicate [ , thisArg ] )

  1. Let O be ? ToObject(this value).

  LengthOfArrayLike ( obj )

  1. Return ℝ(? ToLength(? Get(obj, "length"))).

  ToLength ( argument )

  1. Let len be ? ToIntegerOrInfinity(argument).
  2. If len ≤ 0, return +0𝔽.
  3. Return 𝔽(min(len, 2**53 - 1)).
