Post number three in the new Simples series takes a look at Javascript – a scripting language that adds interactivity to web pages.

It should be noted the Javascript should not be confused with Java (an entirely different programming language).

JavaScript runs on the client side (your browser) and provides interaction with the user and the webpage. It does this by interacting with the HTML in the webpage.

JavaScript is written in plain text and can be saved into a text file with the extension of .js (in the same way that n HTML page, has .html)

JavaScript is a cross-platform, object-oriented scripting language. Adding JavaScript to your HTML code allows you to change completely the document appearance, from changing text, to changing colors, or changing the options available in a drop-down list, or switching one image with another when you roll your mouse over it and much more including animating the transition of elements on a page.
