What is Javascript?

What Makes a Web Page Interactive?

There are millions of people who, when clicking on a web link are surprised to discover that they have caused a form of interaction. The reaction has been caused by the implementation of a form of programming language known as JavaScript.

Known to programmers as probably the most powerful and flexible client-side programming language available, you will find JavaScripts embedded in the majority of web sites as well as the World's leading web browsers such as Internet Explorer, Firefox, among others. The presence of JavaScript enables the processing engine to activate individuals codes contained within the script. When the code is activated through a variety of actions by the browsers, usually by clicking on mouse, or sometimes by simply passing the mouse over a piece of graphic, a reaction will occur.  With more and more uses of Javascript being put on the web every day, those reactions can be pretty interesting.

What Brought JavaScript About?

Before JavaScript became available to web designers and producers, web pages could be pretty dull and uninteresting. Not only that, but the highly important function of establishing an online dialog was a fairly ponderous process. JavaScript has changed all that. Programmers who are adept with the software are capable of producing web pages that present a variety of special graphic effects as well as allow the browser to perform some pretty complicated calculations: order and pay for goods and services online, as well as write a note without the need to exit the web site.

For the web site owner (not to mention those who design and produce web sites) the development of JavaScript has proved to be a major breakthrough. JavaScript is a client-side language, meaning that all the features that it has at its disposal are available in real time, meaning that whatever browser is being used is not required to refer to the server, cutting down on time delays and making the interactivity experience smooth and enjoyable for the surfer .

Although there are now several competing programs, JavaScript remains the most popular simply because of its simplicity of use as well as the many functions it has at its disposal.
