Introduction to JavaScript

It’s important to understand the difference between Java and JavaScript. Java is a full programming language developed by Sun Microsystems with formal structures, etc. JavaScript is a scripting language developed by Netscape that is used to modify web pages. Most JavaScript must be written in the HTML document between <SCRIPT> tags. You open with a <SCRIPT> tag, write your JavaScript, and write a closing </SCRIPT> tag. Sometimes, as an attribute to script, you may add “Language=JavaScript” because there are other scripting languages as well as JavaScript that can be used in HTML. (more…)
