<h2>What You Should Already Know</h2>
<p>Before you continue you should have a basic understanding of the following:</p>
<ul>
<li>HTML </li>
<li>JavaScript</li>
<li>XML</li>
</ul>
<p>To study these subjects first, find all the tutorials you need on our
<a href="../default.asp">Home Page</a>.</p>
<hr />
<h2>JavaScript = ECMAScript </h2>
<p>ECMAScript is the official name for JavaScript.</p>
<p>ECMAScript is the same as
JavaScript.</p>
<p>ECMA (The European Computer Manufacturers Association) is the organization
standardizing JavaScript.</p>
<hr />
<h2>E4X = JavaScript for XML</h2>
<p>E4X means "ECMAScript For XML". It is a standard extension to ECMAScript.</p>
<p>So in real life E4X means "<b>JavaScript for XML</b>".</p>
<hr />
<h2>XML As a JavaScript Object</h2>
<p>E4X is an official JavaScript standard that adds direct support for XML.</p>
<p>With E4X, you can declare an XML object variable the same way as you declare a Date or
an Array
object variable: </p>
<table class="ex" width="100%" border="1" cellspacing="0" id="table1"><tr><td>
<pre><b>var x = new XML()</b></pre>
<pre>var y = new Date()</pre>
<pre>var z = new Array()</pre>
</td></tr></table>
<p>E4X makes scripting for XML with JavaScript very
simple.</p>
<p>Examples are provided in the next chapter.</p>
<hr />
<h2>E4X is a Web Standard</h2>
<p>ECMA-262 (JavaScript 1.3) was standardized in December 1999.</p>
<p>E4X is an extension of JavaScript that adds direct support for XML.</p>
<p>ECMA-357 (E4X) was standardized in June 2004.
</p>
<hr />
<h2>ECMA International</h2>
<p>ECMA International was founded in
1961.</p>
<p>The ECMA organization is dedicated to the standardization of Information and
Communication Technology (ICT) and Consumer Electronics
(CE).</p>
<p>ECMA has developed standards for</p>
<ul>
<li>JavaScript</li>
<li>C# Language</li>
<li>International Character Sets</li>
<li>Optical Disks</li>
<li>Magnetic Tapes</li>
<li>Data Compression</li>
<li>Data Communication</li>
<li>and much more</li>
</ul>
