Web browsers are applications for displaying web pages. A host of special-purpose languages has developed to control their operation. Client-side scripting generally refers to the class of computer programs on the web that are executed client-side (by the user's web browser) instead of server-side (on the web server). The scripting technology is an important part of the Dynamic HTML (DHTML) concept which enables web pages to have different and changing content depending on user input, environmental conditions, or other variables. more...

Java technology is an object-oriented, platform-independent, multithreaded programming environment. It is the foundation for Web and networked services, applications, platform-independent desktops, robotics, and other embedded devices. The Micro Edition of the Java Platform meets the needs of developers creating applications for the consumer and embedded markets. No other technology provides such robust applications across so many types of size-constrained wireless and wireline devices, from mobile phones and PDAs to set-top boxes and vehicle telematics. more...

Tools were originally simple and light weight. As some tools have been maintained, they have been integrated into more powerful integrated development environments (IDEs). These environments consolidate functionality into one place, sometimes increasing simplicity and productivity, other times sacrificing flexibility and extensibility. more...
