Modern browsers improve their engines to raise JavaScript execution script, fix bugs and try to follow the standards.

It's great to see that that new standards, HTML5, EcmaScript are still compatible with the previous code, so they cause no problems with existing applications.

As of now, JavaScript is unique due it's full integration with HTML/CSS and wide browser adoption.
Other languages like CoffeeScript and TypeScript can help to develop faster and write less bug-proof code. It is recommended to take a look at them, at least briefly, after mastering JavaScript.
