Of the two, JavaScript enjoys greater popularity and you can use it on more
than one platform. Consequently, the scripting examples in the book rely on JavaScript.

WORKING WITH SCRIPTS
NOTE
You??™ll find that JavaScript comes in several slightly different forms and names. Besides
JavaScript, you??™ll see this language as LiveScript, JScript, and ECMAScript. You can find an interesting
language history at

Learning the Basics of JavaScript
This chapter doesn??™t provide a nuts and bolts discussion of JavaScript. I??™m assuming you have
some experience using this language. Because this language is used in so many ways, you can find
great JavaScript resources online. Many sites include tutorials, a reference, and sample code. If you
want to be sure your code runs in as many environments as possible, make sure you download a
copy of European Computer Manufacturer??™s Association (ECMA) standard 262 from
http://
www.ecma-international.org/publications/standards/Ecma-262.htm
, which is the standard
for JavaScript.
If you??™ve never used JavaScript before, you??™ll need a good tutorial.
