JavaScript is the world’s most popular language – it is virtually everywhere. And once you learn it (or you’re already familiar with it from some browser scripting) you can leverage it to accomplish a great deal of programming and automation tasks.

- choose node.js for your next server-side web app
- automate sysadmin tasks with JavaScript shell scripts
- improve your (and your visitor’s) browsing experience with bookmarklets and browser extensions
- automate common PhotoShop tasks
- extend some of your favorite apps (e.g. DreamWeaver)
- create desktop GUI apps that run on Windows, Mac and Linux using XULRunner
- create iPhone and Android apps with Titanium or PhoneGap
