What is the difference between != null and !== null?
<p>Sorry for what I'm sure had have been asked in the past, but it's very hard to search for a question like this. "!=" and "!==" are not exactly search friendly. If anyone knows a duplicate question you can point me to it.</p>

<p>What is the difference between doing <code>myVar != null</code> and <code>myVar !== null</code>?
I know that <code>!=</code> is <code>not equal</code> and <code>!==</code> is <code>not equal value or not equal type</code>, but when comparing to null is there ever a case where they would return different results? Is one better to use than the other?</p>
