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. You'll learn why this powerful feature subset is more reliable, readable, and maintainable than the language as a whole, and discover firsthand how to create extensible and efficient code with it. Watch a preview now.
