Mozilla Extending Javascript?

Posted by Zonk on from the busy-little-devs dept.

Nomad128 writes "Mozilla's Deer Park 1 Alpha RC appears to have extended the Javascript spec for the first time in quite some time. New features include Array object methods "every" (logical AND), "some" (logical OR), "map" (function mapping), and "forEach" (iteration). They also appear to have added native XML support. Will this speed up the development of AJAX applications and give Moz a leg-up over IE7?"

    I don't think the Javascript extensions will be used very much. Personally, I'm coding Javascript that will work in most browsers, which means I have to specifically exclude this new Javascript unless IE et al also implement it (and even then, older browsers still won't like it). Not to be anti-Mozilla, but this does sound a bit like embrace and extend to me. (Yes, I know it's open source and others can read the specs.)

    On the other hand, it looks like the things that they did add were mostly based on standards and the DOM spec, so we'll see where this goes.

      As a XUL developer I welcome these additions that will make the language more pleasant to code in.

      They shouldnt be used where they impact on cross browser compatibility though.

    Great.

    So, people used to get pissed off about Microsoft playing around with scripting features in IE that weren't available on other platforms, but now it's going to be an *advantage* for Mozilla?

    Hello-o-oo-oooo-o-ooooo...

    Great more exstentions, more media I want to block, ugh...

    I don't think you have any idea what you're talking about. These extensions to JavaScript will make the language easier to program in, which will be nice for the parts of Mozilla that are written in JavaScript (quite a bit, actually) and for things like Firefox extensions. It doesn't sound like they'll provide any undesirable functionality - we're not talking about floating popup windows here.

    Why can't anyone write something to block all of this stuff out, I don't want to see graphics, or animations, or hear sounds,

    That's precisely what several Firefox extensions do, and these additions to JavaScript will make extensions like that easier to write and maintain (and probably faster to use and smaller to download).

    I love Opera, and it is my browser of choice but I still have to deal with unwanted flash animations.

    Well, maybe you should switch to Firefox with the FlashBlock extension. Or if you really never want to see Flash animations, you could always uninstall the Flash plugin...
