History
"Java" was a programming language invented to run machines, like televisions, radios, remote controls, and refrigerators. But when the World Wide Web became popular, they thought Java was actually very usefull on websites, and soon every browser was capable of running little Java Micro-applications on websites. Nowadays they are known as "Java-applets". JavaScript was first released under the name "LiveScript", as a part of Netscape
Navigator 2.0.
"Can we do just Java, or do we need another language?"
Brendan Eich
It was invented by the programmer Brendan Eich. When LiveScript was renamed it was called "JavaScript", because the basics were the same as Java (don't confuse "Java" with "JavaScript"!), but instead of building little applications JavaScript was used for scripting. JavaScript is used for make static HTML websites dynamic. All this led eventually to DHTML (Dynamic HTML). DHTML is no independent language, but a mix of HTML (for structure), CSS (for styling) and JavaScript.
JavaScript abuse
Unfortunetaly some people make things with JavaScript that makes you go crazy. You have to click 100 times on an alert message before you may close the window, or you get five Pop-Up windows with advertising and commercials with every click. That is why many browsers (application to watch websites, such as Internet Explorer or Firefox) added a function to turn off JavaScript. But the sad thing is that many great features on good-willing websites are unabled as well. That is why I advise you to unlock JavaScript on safe websites, such as Google, Wikipedia and of course my own website.
