Douglas Crockford is the author of How JavaScript Works. He has been called a JavaScript Guru, but he is more of a Mahatma. Doug was born in Frostbite Falls, Minnesota, but left when he was only six months old because it was just too damn cold. He has worked in broadcasting, learning systems, small business systems, office automation, games, interactive music, multimedia, location-based entertainment, social systems, and programming languages. He is the inventor of Tilton, the ugliest programming language that was not specifically designed to be an ugly programming language. Doug is best known for having discovered that there are good parts in JavaScript. That was the first important discovery of the Twenty First Century. He also discovered the JSON Data Interchange Format, the world’s most loved data format.
