Javascript (full-stack) will be running at least half of the most popular websites within 5 years.

Doubt that. Language preferences don't change that fast. PHP, Python, Ruby are extremely strong. Plus there's Go, which seems like an awesome language.

That's a very, very, very, bold statement! Not saying you're right or wrong, but venerable technologies have a tough time dying quietly. Also most developers tend to be fairly conservative with what they choose especially when load and performance is concerned.

Again... Good luck with parallel code.

  yeah web workers have been driving me nuts recently. The debugging - or lack of it - is crazy.
  - erichocean 14y ago
    You can debug web workers in Chrome's normal debugger. It has a separate debugger instance for each worker.

  >Again... Good luck with parallel code. Err, people have moved on from straight parallel code. It's all about message passing and isolation now, which is something Javascript can get perfectly easily (and sort of already has).

    Lol no.

    First, it's the browser that has web workers, not javascript. Second, message passing is prohibitively slow for things like, say, video games. Third, it's not clear at all that we gain any benefit from javascript use.

> most popular are you talking about the top-10 websites? let's take them one by one: - Google. I don't think so, it's not even one of their major server-side languages now. - Facebook. Likewise. - YouTube. See Google. - Yahoo!. I don't know anything about their server-side - QQ.com, Taobao.com, Baidu.com. Given that the Chinese do not pioneer web platforms, I don't see why they'd do this. - Windows Live. I know MS "likes" JavaScript, putting it in Windows and all, but it's not one of their major languages. It's not even their own :P - Wikipedia. Would require a switch from MediaWiki or rewrite. While I'd very much like to see PHP replaced, it's currently doing it's job. I have a feeling the language does not matter much, MediaWiki itself is not very complicated. - Amazon.com. Don't know. Do you seriously see 5 or more of these turning to server-side JS?

  Top 10 is impossible to say since we don't know who will be in those slots 5 years from now. Internet time is insanely fast. Things come and go very quickly. I think it'd be fair to say half of the Top 1000 sites will be with the rate of Node's current development. Development is now getting to a point where they aren't going to be adding new features, but focusing on making it as efficient as possible in what it is (give this a listen http://javascriptjabber.com/052-jsj-node-npm-with-isaac-schlueter/ http://javascriptjabber.com/052-jsj-node-npm-with-isaac-schl...). I made the switch recently from PHP and I don't think I'd ever go back. Love it, although yes there is a slight learning curve but if you know Javascript already you'll do fine. Knowing how to use callbacks and using some sort of middleware like express is the way to go when developing applications with it.

  - Amazon.com. Don't know. Very unlikely; Amazon's backend is basically Perl talking to an SoA via an internal service definition language. A change to server-side JS would require a re-write of almost everything (which isn't unprecedented; the migration from a single giant C++ binary to the Perl system 10-odd years ago was such a rewrite).
