JavaScript Master Class Video

The Douglas Crockford JavaScript Master
Class — In this Master Class video, Douglas will scrape away the language's bad features to reveal all the good ideas that make JavaScript an outstanding object-oriented programming language -- ideas such as functions, loose typing, dynamic objects, and an expressive object literal notation.

Watch a preview now.
