JavaScript has quickly become a ubiquitous part of World Wide Web infrastructure. Very few Web sites of any sophistication can operate without the benefit of this technology. The Builder QuickStart Tool: JavaScript will give you the information you need to take advantage of what JavaScript has to offer.
JavaScript
The Builder QuickStart Tool: JavaScript explains how the ECMA released the first edition of the ECMAScript Language Specification in an effort to standardize the JavaScript technology. As an interpreted language, JavaScript requires an interpreter to execute, and, therefore, does not need to be compiled like many programming languages. This makes JavaScript ideal for client-side processing in Web applications, and is why most modern Web browsers have built-in JavaScript interpreters.
To acquaint you with JavaScript syntax, the Builder QuickStart Tool: JavaScript presents the basic "Hello World" program, as shown in this excerpt:
Hello World program
Here is the simplest form of a "Hello World" program using client-side JavaScript:
<HTML>
<SCRIPT language="JavaScript">
document.write("Hello World!"); </SCRIPT>
</HTML>
Save it as "HelloWorld.html" and open it in a modern browser to see it execute.
The Builder QuickStart Tool: JavaScript then takes the "Hello World" program one step further by showing you how to use event handlers and buttons to make a more substantial user experience.
