Is Javascript free Where do I find it and load it?

Answer 1

It's not a program, it's a language.

So yes, it's free. But you can't "find it" or "load it"!

If you mean Java, that's also a language but you can download the Java runtime environment from sun microsystems

And yes, it's free.

Answer 2

As other have pointed out, JavaScript is just a scripting language.

Being a scripting language it needs something called an "interpreter" which executes a script you've written in the language.

The good news is that if you have a modern web browser, such as Firefox or Internet Explorer or Safari, your computer already has such an interpreter, since all three of three of these browsers support interpreting JavaScript.

If you'd like to write a really quick and simple script, try this:

In the location bar of your web browser (where you would type in the address of a web site you wanted to go to; like http://www.yahoo.com) type:

javascript:document.body .style.background = "red"

(that should be all on one line)

and hit "enter". The background of the page you are will turn red.

You can also try things like:
javascript:alert(Math.PI * 2 + 5)

(the part after javascript: is the actual script; javascript: just tells the browser to evaluate it).

For a good overview of JavaScript you might want to read the Wikipedia article about it:
http://en.wikipedia.org/wiki/JavaScript

Additionally, this article from about.com provides a nice introductory tutorial:

Answer 3

what do you want for javaScript? it is a kind of programming language that written for web page. it is written by programmer to build a program. thus, if you want a certain program that's written in javaScript, you need to look for programmer( you've to pay) or goto learn and write yourself( it's free).
