JavaScript

JavaScript is a programming language commonly used to enhance webpages. It is a client side language, meaning that it executes on the computer that the page is being read on, as opposed to server side scripts, which are executed on the web server, and the result is transmitted to the viewer. Because it is a client side language, JavaScript does pose some additional security concerns and modern browsers have the option to turn JavaScript off.

JavaScript allows developers to create webpages that change.
