JavaScript: the good parts

If your brain hasn't been polluted with awful JavaScript practices yet (or if you're willing to submit to a proper brainwashing), read the JavaScript: The Good Parts book from Douglas Crockford. He covers what he believes (and is usually right) are the good parts of JavaScript, resulting in scalable, easy-to-maintain code. Although the book targets beginner audiences (or programmers not yet familiar with JavaScipt), it's an interesting read for anyone who wants to write better JavaScript code. Even I found a few interesting topics (for example, multiple ways to implement object constructors and inheritance) after working with JavaScript for 15+ years.
