JavaScript Pocket Reference [PDF ebook] 

Java Script is a powerful, object-based scripting language that can be embedded directly in HTML pages. It allows you to create dynamic, interactive Web-based applications that run completely within a Web browser — Java Script is the language of choice for developing Dynamic HTML (DHTML) content. Java Script can be integrated effectively with CGI and Java to produce sophisticated Web applications, although, in many cases, Java Script eliminates the need for complex CGI scripts and Java applets altogether.The Java Script Pocket Reference is a companion volume to Java Script: The Definitive Guide. This small book, covering Java Script 1.2, is a handy reference guide to this popular language for Web development. It provides a complete overview of the core Java Script language and contains summaries of both core and client-side objects, methods, and properties.
