description: >
  Throws a TypeError exception if predicate is not callable.
info: |
  22.2.3.10 %TypedArray%.prototype.find (predicate [ , thisArg ] )

  %TypedArray%.prototype.find is a distinct function that implements the same
  algorithm as Array.prototype.find as defined in 22.1.3.8 except that the this
  object's [[ArrayLength]] internal slot is accessed in place of performing a
  [[Get]] of "length". The implementation of the algorithm may be optimized with
  the knowledge that the this value is an object that has a fixed length and
  whose integer indexed properties are not sparse.

  22.1.3.8 Array.prototype.find ( predicate[ , thisArg ] )

  ...
  3. If IsCallable(predicate) is false, throw a TypeError exception.
