SOME CLAIM THAT JAVASCRIPT is now the most popular programming language in the world, running
any number of complex web applications that the world relies on to do business, make purchases,
manage processes, and more.
JavaScript is very loosely based on Java, an object-oriented programming language popularized
for use on the Web by way of embedded applets. Although JavaScript has a similar syntax and
programming methodology, it is not a “light” version of Java. Instead, JavaScript is its own
dynamic language, fi nding its home in web browsers around the world and enabling enhanced user
interaction on web sites and web applications alike.
In this book, JavaScript is covered from its very beginning in the earliest Netscape browsers to the
present-day incarnations fl ush with support for the DOM and Ajax. You learn how to extend the
language to suit specifi c needs and how to create seamless client-server communication without
intermediaries such as Java or hidden frames. In short, you learn how to apply JavaScript solutions
to business problems faced by web developers everywhere. |
