This short and digestible summary of JavaScript 1.5 (ECMA-262, Edition 3 specification) focuses on the nature of objects in JavaScript, giving you an accurate JavaScript worldview through an examination of native JavaScript objects and supporting nuances: complex values, primitive values, scope, inheritance, the head object, and more. If you're a designer or developer who has only used JavaScript under the mantle of libraries - such as jQuery and Prototype - the material in this book will help transform you from a JavaScript library user into a JavaScript developer.
