Beginning Javascript 4th edition

JavaScript is a scripting language that enables you to enhance static web applications by providing dynamic, personalized, and interactive content. This improves the experience of visitors to your site and makes it more likely that they will visit again. You must have seen the fl ashy drop-down menus, moving text, and changing content that are now widespread on web sites — they are enabled through JavaScript. Supported by all the major browsers, JavaScript is the language of choice on the Web. It can even be used outside web applications — to automate administrative tasks, for example.
