When we talk about instruments, sometimes the guitar gets all the credit. Of course guitars are great, but an electric guitar on its ownâeven a hollow-bodyâis only so loud. For giving one of the world's favorite instruments its voice, guitar amplifiers deserve a little love too.
This book treats JavaScript as a serious object-oriented language, showing you how to build robust, maintainable, and powerful libraries and applications. Along the way, we cover many of the recent innovations such as AJAX, JSON, and interesting design and coding patterns.
Object-orientation's longevity can largely be explained by the fact that the ideas at its core are very solid and useful. In this chapter, we will discuss these ideas, along with JavaScript's (rather eccentric) take on them. The above paragraphs are by no means meant to discredit these ideas.
