What you'll need
You don't need any special software to write JavaScript. All you need is a plain text editor and a web browser.
Code written in JavaScript must be executed from a document written in (X)HTML. There are two ways of doing this. You can place the JavaScript between <script> tags within the <head> of the document:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html>
<head>
<script type="text/javascript">
