<h2>Complete Boolean Object Reference</h2>

<p>The reference contains a brief description and examples of use for each

<h2>Boolean Object</h2>
<p>The Boolean object is an object wrapper for a Boolean value.</p>
<p>The Boolean object is used to
convert a non-Boolean value to a Boolean value (true or false).</p>
<p>We define a Boolean object with the new keyword. The following code line
defines a Boolean object called myBoolean:</p>
<table class="ex" cellspacing="0" border="1" width="100%" id="table1">
<tr>
<td>
<pre>var myBoolean=new Boolean();</pre>
</td>
</tr>
</table>
<p><b>Note:</b> If the Boolean object has no initial value or if it is 0, -0, null, "", false,
undefined,
or NaN, the object is set to false. Otherwise it is true (even with the string
"false")!</p>
<p>All the following lines of code create Boolean objects with an initial value
of false:</p>
