Is it good practice to delete no longer used objects and variables in JavaScript?
<p>In my code I use an object and variables inside a function. When in that function I no longer use the object and variables I delete it:</p>

<pre><code>delete myObject;
delete myVar;
</code></pre>

<p>Is it good practice?<br>
Does it give speed?</p>

<p>My JavaScript is server-side on smart.joyent.com.</p>
