JavaScript

JavaScript is a way to make webpages interactive. In a server-side scripting language like PHP or ASP, the code that you write runs on the server that your website is hosted on. The server then sends plain HTML to the visitors' browsers. JavaScript is a client-side scripting language, which means that it runs on your browser. If the website visitor has JavaScript turned off, the code won't run and the webpage won't be interactive. That is one of the drawbacks of JavaScript. The advantage of JavaScript is that you can do great things with it that can't be done with server-side scripting alone.

Note: JavaScript is unrelated to Java -- they are totally different languages.
