Firefox 27(Nightly) における新たな String.prototype["@@iterator"] - hogehoge @teramako
928508 – String.prototype.@@iterator (and thus for-of) incorrectly iterates over code units rather than Unicode characters ちょいと面白いものが実装されて、String.prototype["@@iterator"]がアップデートされてた。 "@@iterator" というのは、ECMAScript 6th におけるイテレータとなるメソッドで、最近注目のジェネレータオブジェクトを返す。*1 で、このジェネレータオブジェクトのnextメソッドが、従来であればインデックス値に沿って順に値を返していたのだが、これからはUnicodeポイントに沿って値を返すようになる。UTF-16 においてサロゲートペアとなるような文字は従来は2文字として扱われていたのが、Unicodeポイン

Regenerator
Several months have passed since support for generator functions and the yield keyword arrived in Node.js v0.11.2. This news was greeted with great excitement, because generator syntax provides a much cleaner alternative to using callbacks when writing asynchronous server-side code. One of the biggest benefits of using JavaScript on the server is that you can (in theory at least) run the very same
