  22.2.3.15 %TypedArray%.prototype.join ( separator )

  %TypedArray%.prototype.join is a distinct function that implements the same
  algorithm as Array.prototype.join as defined in 22.1.3.13 except that the this
  object's [[ArrayLength]] internal slot is accessed in place of performing a
  [[Get]] of "length".

  22.1.3.13 Array.prototype.join (separator)

  ...
  4. Let sep be ? ToString(separator).
  5. If len is zero, return the empty String.
