<p class="description">
When using two equals signs for JavaScript equality testing, some funky conversions take place.
</p>
</div>
<div id="three-equals">
<h2>=== <smaller>(negated: !==)</smaller></h2>
<p class="description">
When using three equals signs for JavaScript equality testing, everything is <b>as is</b>. Nothing gets converted before being evaluated.

<div id="if-statement">
<h2>A standard IF statement. If(<i>value</i>) {/*- green -*/} else { /*- white -*/ }</h2>
<p>Note: This row does not match up with any of the rows in the other table.</p>

<h4>Moral of the story:</h4>
<p>
Always use 3 equals unless you have a good reason to use 2.
