I avoid it because JavaScript is a suck ass language.

Don't you mean most browsers' implementation of JS is suck ass, or more to the point, the DOM API for different browsers? In my experience, all the browsers implement the language in a similar fashion and the only inconsistency between browsers might be which version is implemented (i.e JS 1.2 vs JS 1.5). I can't vouch for the various DOM APIs as I have mostly avoided them due to a particular distaste for DHTML, but from my brief experiences the DOM API differs from IE to Netscape to $other and is quite hellish to get anything working consistently across browsers.

I'd also have to say Javascript as a language is quite wonderful indeed. Its got your OO, first-order functions, lexical scoping and as of later versions there is regex support and exceptions (1.3 and 1.5 respectively). So quite perl like in a lot of ways with its polymorphic variables, open-ended OO system and many many clueless hackers (although the JS 'community' doesn't have anywhere the same amount of clued-up hackers as perl does unfortunately).
