<p>I am more and more working with javascript, especially with JQuery for web site and node.js for server side (really like node.js though) and I quite often struggle to understand the inner structure of the language (such as prototypes, asynchronous function, ...).  </p>

<p>What are the best articles, or so, that could help a developer to leverage his competency in this language (that is really worth learning IMHO).</p>
