In this tutorial, we will setup a Node.js development environment, which allows you to include rapidly new team members into the development process of your Node.js applications. This method can also be applied if a developer wants to create several versions of an application simultaneously.

Every byte counts when you’re sending files via HTTP and best practices dictate that on a production, you need to optimize all of your files to minimize page load times. Compressing JavaScript code is one of the easiest ways to do that and these tools will help. On the jQuery project, we’ve started using Google’s Closure compiler because it’s generated the best compression. Try all of them out to see which suits you best.

I definitely recommend everyone to learn JavaScript as you’ll need it to be a really effective client-side developer. With that said, a good JS library will go a long way to making your development faster and much more stable. These libraries are all very mature and dramatically help to abstract the complexities of cross-browser development. My personal favorite is jQuery, of which I’m a member of the project team.
