Quickly ran though "Getting Good with JavaScript", this is a very short and basic introduction to JavaScript for someone new to the language. Deep and difficult concepts are avoided or explained in an easy to understand way for the reader to explore further by him/herself.
I found these two resources in the "Further Study" section very helpful and interesting, both are from Rey Bango's blog:
1. What to read to get up to speed in JavaScript
2. The big list of JavaScript, CSS, and HTML development tools, libraries, projects and books
