In this Master Class video, JavaScript expert Douglas Crockford 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. Based on his popular O'Reilly book, JavaScript: The Good Parts, this class will demonstrate how JavaScript can be a beautiful, elegant, lightweight, and highly expressive language. Most programming languages contain good and bad parts, but JavaScript has more than its share of the bad, having been developed and then released in a hurry before it could be refined.
