Introduction:


First thing is first...we will discuss exactly what JavaScript is, how to manage JavaScript in your browser, what the differences are between Java and JavaScript are and why you might need JavaScript.

JavaScript was developed in 1995 by Netscape and by definiton is: "A scripting language used to create interactive web sites." Java can be included in HTML as php would, or; can be called upon as an external file - like php also. From what I hear, it is one of the easier languages to learn in programming.

Microsoft includes JavaScript with their browser, although it was developed by Netscape. However, their are differences in how each browser supports it. Microsoft Internet Explorer. By default, JavaScript is 'enabled' for a more pleasurable browsing experience. However, JavaScript can have some nasty tricks - and you might want to 'disable' JavaScript completely. Keep in mind though, some websites may require JavaScript to be enabled for their systems to function properly. JavaScript was made for good purposes to provide you with a more interactive, exciting and more pleasurable browsing experience.


JavaScript: The good, the bad and the ugly...

What are the good things JavaScript can do? Why should I browse with JavaScript enabled? Well; as I mentioned before, JavaScript can be used to run entire websites, and If you visit their site and you have it disabled, nothing would work. You may see JavaScript used to make scripts to maintain data and webpages, other various effects from "MouseOver's" to text manipulation, online polls, picture galleries and much more.

Now that we've got an idea of the good things of JavaScript, why would I want to disable JavaScript? Yes; JavaScript can be nasty. Like all good things, some bad is always present. It can be used to flood you with annoying pop-ups, it can move your browser all across the screen, crash your browser and access your IP, as well as many more devious tricks.


If you want an idea of what it might be able to do, pay a visit to one of these sites:

But usually, these are only used by so called "script kiddies" and no professional website or organization would purposly crash your browser or cause you any dis-satisfaction.

So there are some goods and bads of JavaScript. But also before you would decide to just "prompt" you when to permit JavaScript, keep in mind that this can be very annoying. Expecially if you're visiting a site that is mainly controlled by JavaScript. I would recommend "prompting" to the person who is seeking high anomity and security or whatever. The same deal with cookies.
