Even if I’m the NoScript guy, I write a lot of JavaScript all the day. As you probably know, even the JavaScript Annihilator is mostly written in JavaScript. Like Crock, I love the language, despite its current browser-bound shortcomings.

So far, my favourite editor for JS coding has been JEdit with its JavaScript plugin, providing syntax highlighting (of course!), on the fly syntax checking via Rhino and optional code completion with configurable scopes, including Mozilla “chrome window” and XPCOM.

But today I’ve watched a presentation of the new NetBeans 6.1 JavaScript capabilities, and I’m impressed.
Dynamic type guessing, browser-specific contextual help and DOM-aware AJAX library support (John, guess which they show in their demo?) may be really worth the switch.

John Resig (of jQuery fame, now a Mozilla Corp. employee) lets us know that JSON leakage through Array constructor redefinition, one form of so called AJAX-hijacking working on Opera, Safari and Firefox, is going to be impossible on Firefox 3.
Starting with next Beta 2, in facts, most built-in global constructors (Array, Boolean, Date, Math, Number, Object, RegExp, String) will be constant: override attempts will raise an error.
This is obviously an incompatible change, even though the “broken” functionality shouldn’t be something you rely upon in your everyday web application.
Anyway, if you find any regression, this is currently tracked under Bug 376957.
