More info

JavaScript, not to be confused with JAVA is a programming language specially adapted to the needs of web programmers. The scripts written in it are processed by the browser and allow a website to be changed dynamically. This does not happen on the web server, but in the browser of the user. Therefore, there is some security risk with JS files.

However, JavaScript is very common and many modern offers, often referred to as WEB 2.0, do not work without JavaScript processing.

The JS file contains the source code, but it does not have to be pure JavaScript. It can also be based on one of the numerous JavaScript libraries, such as Mootools or jQuery. Even AJAX applications like Google Maps use JavaScript.

To edit a JavaScript file, a simple text editor is sufficient, but a special editor is preferable. This recognizes the language elements, presents them color coded and structured.

Any browser can execute JavaScript, but the results are quite different.
