Dave Herman: The Future of JavaScript

Mozilla Labs engineer and TC39 representative Dave Herman joined us at YUIConf 2011 to give this keynote talk on the future of JavaScript, covering many of the new features currently under consideration for ES6, the next edition of the ECMAScript standard.

Looks brilliant. Someone had better start writing the legacy browser shim library now so that we can be using all this goodness within 10 years of its release. Erm, not me though, I'm kind of busy and stuff... :)

Hey, did you read Crockford "The Good Parts"?

JS is perfect, it's just DOM API in browsers that sucks!

Good luck, study, study, study and then teach your colleges;)

i pretty much hate javascript too. What i hate it is b/c theres too many ways to do one thing. Its too open/flexible for its own good. And its even worse when working with someone else's javascript. I don't particularly like jquery's programming strategy either, the programmer has to keep track of the long as hell chained objects in on statements....not good for passing around code, that much for sure.

Thanks for the information, great job...

Do not make the language application dependent, most of the additions not useful. I like JavaScript it makes no assumptions, after 32 years of development I am trying to learn how to not make assumptions and I am constantly trying to simplify my code (language independent), and I use no abbrivations.

My recommendations: “structure” “new ByteString()”

“get function name(...)” “set function name(...)” "read" "write" "open(url-spec or file-spec)"

I don't like that classic example code. Yes, it is classic, but yes, it is tragic as well. There's no implied (at least for .txt files) reason for synchronizing those GET requests. In that case, it's best to just effectively fork/join the requests. Fire off as many as is reasonable at once and when all of them have completed, yield back to the caller. Since JS is (presently) guaranteed to be single threaded, writing the join part is really simple.

This is very good video looking nice & attractive.Thanks for sharing & posting this video.I really liked your video youtube can be a great asset for you.It is very informative for those users who want to know about future of java script.

[TheProgrammer93]

As a programmer I can officially say that JavaScript is, and has always been, a piece of shit.

[Jerome Wilson]

Thinking about it, maybe shimming is best handled by, for instance, a CoffeeScript compiler... Oh hang on I'm just getting around to watching the last 5 minutes of the talk, looks like this might be covered...

All hail Pyscript!

@iglor, because arguments includes all passed-in arguments, including those that are explicitly declared in the function signature. So you have to count your arguments and shift/offset accordingly. Also, unlike 'this', 'arguments' is not a reserved word, which lets people do stupid stuff, like overwrite it.

[iglor]

Too much adding, too less fixing. Who needs ..rest if arguments was an array?
