FAQs about this language.
What is JavaScript?
So what exactly is JavaScript? Well, it's is a scripting language developed
by Netscape to add interactivity and power to web documents. Examples of
JavaScript include live clocks, rollover effects, scrollers, form
validations, and so on. JavaScript differs from most other programming
languages in that it is relatively easy to master, even for people who have
absolutely no programming experiences whatsoever.
Why learn JavaScript?
The first few words that come to mind are: "Freedom baby, freedom!" With
html, you are restricted to creating static, non interactive webpages. This,
in today's internet standards, is unacceptable. With JavaScript, you can
change that. Imagine being able to break free and allow your creativity to
dictate what you put on your webpage, instead of the other way round. And
the best part is, JavaScript can be learned by anyone-yes, I said anyone!
What's the difference between Java and JavaScript?
Java is completely different from JavaScript-It's a lot more powerful, more
complex, and unfortunately, a lot harder to master. It belongs in the same
league as C, C++, and other more complex languages. Also, you need to
compile a Java program before you can run it, whereas with JavaScript, no
compilation is needed-simply open up a text editor, type it, save it, and
your browser is ready to run it!
Can my JavaScript programs run on both Netscape and Internet
Explorer browsers?
Unfortunately, not necessarily. JavaScript was created by Netscape,
so it is most compatible with Netscape. Internet Explorer 4.x supports 99%
of what JavaScript has to offer, although IE 3.x is not quite as adorable. A
good rule to follow is to always test your codes using both browsers before
uploading it onto the internet. You will be surprised how many websites fail
to do this, annoying surfers and not even realizing that their scripts are
going haywire behind their backs! (this might pertain to me too)
