No. One of the improvements to JavaScript since ES5 (you know, those things you keep objecting to) is that strings are now iterable, and the iteration visits *characters* (codepoints), not code units. (Example: https://jsfiddle.net/03tLpbrv/) (Also worth noting that JavaScript strings were never ASCII-centric. They were UTF16-centric [with invalid surrogate pairs tolerance].) If there were a `.map` added, it would presumably visit characters, not code units, as well; it would be the only reasonable thing to do, both in light of how strings iterate and just general utility/appropriateness. -- T.J.
