It's not the most correct way to do it. |a + ""| performs ToPrimitive(a, hint = None), whereas ToString(a) performed ToPrimitive(a, hint = String). The former consults valueOf, then toString, the latter the reverse. > using String(any) to invoke ToString is verbose and fragile, because String > could be rebound :-P. Generally polyfills are fine with that limitation, and only us language pedants need worry/care about String being rebound. All the array-method polyfills we've provided on MDN depend on non-rebinding of some builtin function or other. It's not that big a deal.
