I have to agree with Luke here. Tiny bit of pedantry: using arrows for functions is not new at all, it has been fairly common for functional languages for at least twice as long as the total age of JavaScript. The only more recent news is that it has also trickled into the mainstream over the last decade. /Andreas _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
