If you create a fantastic web page with HTML and CSS you will always think of new ways to improve it and make it more fun to use. In that case you’ll probably use Javascript.

Javascript is a programing language that you can use to control your webpage and the way it behaves. In the same way CSS controls the look of the web page.

You’ve probably seen quie a bit of Javascript in action with out realizing it. Javascript is often use on menues and navagation. The only problem with this is that Javascript can not be user friendly if not used correctly.

 

In the last 2-3 years i have had no pop ups because most browsers and security programs stop them. But before then you will properly remember when you would get pop ups advertising on thing or another. 

Beware РJavascript is not the same a Java they are two different languages witch are similar. Javascript inventors called it Live script when it was created  but rename it as a marketing ploy when Java became popular.
