I also partly agree with with Douglas Crockford that Javascript is now good language - at least as Douglas says in his book - as you use the "The good parts" there.

Here is a quote:

 "The first is that you don't have a choice. The Web has become an important platform for application development, and JavaScript is the only language that is found in all browsers. It is unfortunate that Java failed in that environment; if it hadn't, there could be a choice for people desiring a strongly typed classical language. But Java did fail and JavaScript is flourishing, so there is evidence that JavaScript did something right.
The other answer is that, despite its deficiencies, JavaScript is really good. It is lightweight and expressive. And once you get the hang of it, functional programming is a lot of fun."
