"How do I get started with Node?" is a commonly heard question in #Node.js. This gist is an attempt to compile some of the answers to that question. It's a perpetual work-in-progress.

And if this list didn't quite answer your questions, I'm available for tutoring and code review! A donation is also welcome :)

Setting expectations

Before you get started learning about JavaScript and Node.js, there's one very important article you need to read: Teach Yourself Programming in Ten Years.

Understand that it's going to take time to learn Node.js, just like it would take time to learn any other specialized topic - and that you're not going to learn effectively just by reading things, or following tutorials or courses. Get out there and build things! Experience is by far the most important part
