You don't need to buy a book until you want advanced help.
The tutorials on the internet already should suffice for the beginner.
When you understand those examples, you can move on to a text to purchase.

Try a google of "free javascript tutorial" and chose which ever looks the closest to your level of understanding. :thumbsup:

And as for "latest version of JavaScript": Irrelevant. You *must* write your code to work with all the popular browsers and that means you have to determine how far back you want to go in trying to write cross-browser code.

Most people now are still supporting MSIE version 7, along with Firefox, Chrome, and Safari. But of course then there is mobile support, which involves even more testing to be sure your code works in the desired devices.

Personally, I initially write for Firefox 3.6 (or later) and then test my code in MSIE 7. When it works in both of those, then I check it in other browsers. Most of the time, if it works in those two it works in all.

Finally, JavaScript itself hasn't changed much in over 12 years. It's really the DOM (Document Object Model...the "library") of the browser, as implemented in the various browsers, that will cause you fits.

as of late there are some nice features added, though
- Function.bind() (makes an "implicit Closure")
- object read/write definitions (readable, writeable, enumerable, freezing and locking)

Don't mention the new possibilities opened by the HTML5: web storage, canvas transformation, animation, etc :)

I’d let that fall under the category "DOM"

Where can these new features be found and are they supported by the main browsers yet?

most of the stuff should be available in modern browsers.

like always it is the question if (and in which version) IE supports anything thereof.


test your browser against the latest ECMAScript version: http://test262.ecmascript.org/
