The JavaScript Language and Ajax for Java Developers (SEM-DTJ-2121)

The JavaScript Language and Ajax for Java Developers (SEM-DTJ-2121)
 
Email Product Description

JavaScript is the de facto programming language for developing browser-based web applications that provide the rich functionality traditionally associate with desktop applications (commonly referred to as Web 2.0 applications). This class explains the JavaScript language in terms familiar to a Java Technology Developer, or a developer familiar with other object-oriented langugages, such as C++. Additionally, you will learn tips and tricks for developing web applications that leverage best practices for using client-side JavaScript, and especially the Ajax technique, to provide a richer and more responsive user experience than can be achieved by server-side logic alone.
