JavaScript: The Good Parts

Product Description

Most programming languages contain good & bad parts but Java Script has more than its share of the bad having been developed & released in a hurry before it could be refined. This authoritative book scrapes away these bad features to reveal a subset of Java Script that's more reliable readable & maintainable than the language as a whole-a subset you can use to create truly extensible & efficient code. Considered the Java Script expert by many people in the development community author Douglas Crockford identifies the abundance of good ideas that make Java Script an outstanding object-oriented programming language-ideas such as functions loose typing dynamic objects & an expressive object literal notation. Unfortunately these good ideas are mixed in with bad & downright awful ideas like a programming model based on global variables. When Java applets failed Java Script became the language of the Web by default making its popularity almost completely independent of its qualities as a programming language. In Java Script: The Good Parts Crockford finally digs through the steaming pile of good intentions & blunders to give you a detailed look at all the genuinely elegant parts of Java Script including: * Syntax * Objects * Functions * Inheritance * Arrays * Regular expressions * Methods * Style * Beautiful features The real beauty? As you move ahead with the subset of Java Script that this book presents you'll also sidestep the need to unlearn all the bad parts. Of course if you want to find out more about the bad parts & how to use them badly simply consult any other Java Script book. With Java Script: The Good Parts you'll discover a beautiful elegant lightweight & highly expressive language that lets you create effective code whether you're managing object libraries or just trying to get Ajax to run fast. If you develop sites or applications for the Web this book is an absolute must.
