Probably, as javascript will remain the browser's only supported scripting language forever as it's such a big hurdle to get all the browser makers to implement a new language. I imagine javascript in the browser will eventually be like x86 assembler though in that almost everybody will write in a higher level language like coffeescript, or through layers of libraries like jQuery.
