There's exciting stuff happening in all languages. Right now javascript is fashionable in certain highly-visible development communities (like the open-source community, for example). That doesn't mean it's the most popular language, or that it's the right choice for your project. The other factor is that browsers (for mostly historical reasons) only widely support javascript natively. So naturally, most front-end frameworks will be javascript based.
