Last week, I gave a talk at my local meetup about the upcoming standard ECMAScript6. Javascript is definitely starting to look like a decent language, and will have a lot in common with python (destructuring assignment, default parameters and so on).
The most exciting for me is the possibility to implement coroutines using generators and promises. I already blogged about it, but this bear repeating, it will make asynchronous programming much easier.
The talk went smoothly, but I suspect a good 2/3 of the audience did not understant a lot of things, as they were all beginner in javascript. Also kudo to the guys at Mozilla Taiwan to offer us their nice conference room ^^
The slides can be found on github or as a pdf on slideshare.
