What Is JavaScript? — Explains the origins of JavaScript: where it came from, how it
evolved, and what it is today. Concepts introduced include the relationship between
JavaScript and ECMAScript, the Document Object Model (DOM), and the Browser
Object Model (BOM). A discussion of the relevant standards from the European Computer
Manufacturer’s Association (ECMA) and the World Wide Web Consortium (W3C) is also
included.
Considered the JavaScript expert by many people in the development community, author Douglas Crockford identifies the abundance of 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. Unfortunately, these good ideas are mixed in with bad and downright awful ideas, like a programming model based on global variables.
