What new feature has been released in JavaScript in any widely usable way in the last decade?

Funny you should ask that because the internet is just now taking a big lurch forward with Canvas and everything in HTML5. Would Objective-J quickly adopt new features in Javascript or stay closer to developments in Objective-C? Since everything gets compiled down to Javascript in the end (and Objective-J doesn't feature 100% browser compat either) I don't see how they can offer anything not possible with Javascript to begin with. Actually that's a question? I don't understand how it is different than, for example, CoffeeScript - but I would be happy if you could explain how it is.

  It's very similar to CoffeeScript. It is a strict superset of JavaScript, so all valid JavaScript remains valid Objective-J. You also shouldn't confuse the language (Objective-J) with the Cappuccino framework. Objective-J is just about providing certain language level features on top of JavaScript, the same way Objective-C implements features on top of C. It's also 100% cross browser, so I'm not sure what you mean by that. Cappuccino is a full fledged framework for building apps which run in a browser. I'd argue that it's the best, but my opinion would hardly be unbiased. It does in fact implement an API for using Canvas (which also works in IE). Though, that isn't a JavaScript feature. And pretty much nothing in HTML5 is present in 50% of the browsers out there.

  http://github.com/280north/cappuccino/blob/master/AppKit/CoreGraphics/CGContextCanvas.j http://github.com/280north/cappuccino/blob/master/AppKit/Cor... But if you don't like a particular part of the abstraction layer provided by Objective-J/Cappuccino, you're definitely free to use raw JavaScript. Just like in Objective-C you're free to use structs, function pointers, and C-style arrays.

XSL became widely usable in 2007 when Safari 4 was introduced (on the iPhone too). Nobody even noticed.
