  [[Get]] of "length" uses [[ArrayLength]]

  22.2.3.11 %TypedArray%.prototype.findIndex ( predicate [ , thisArg ] )

  %TypedArray%.prototype.findIndex is a distinct function that implements the
  same algorithm as Array.prototype.findIndex as defined in 22.1.3.9 except that
  the this object's [[ArrayLength]] internal slot is accessed in place of
  performing a [[Get]] of "length".
