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.

    They're not extending javascript from what I can see. It looks like they're implementing some features that weren't implemented before.

    I agree, lets bundle it with Linux.
