description: Returns -1 if length is 0

  22.2.3.13 %TypedArray%.prototype.indexOf (searchElement [ , fromIndex ] )

  %TypedArray%.prototype.indexOf is a distinct function that implements the same
  algorithm as Array.prototype.indexOf as defined in 22.1.3.12 except that the
  this object's [[ArrayLength]] internal slot is accessed in place of performing
  a [[Get]] of "length".

  22.1.3.12 Array.prototype.indexOf ( searchElement [ , fromIndex ] )

  ...
  2. Let len be ? ToLength(? Get(O, "length")).
  3. If len is 0, return -1.
