Does it make sense to use === for string comparison in JavaScript?
<p>While it's clear how using the <code>===</code> operator for e.g. numbers is useful (<code>0</code>, <code>null</code> and <code>undefined</code> all being falsy values, which can lead to confusion), I'm not sure if there are benefits to using <code>===</code> for string comparisons. </p>

<p>Some of my team mates use this operator for all comparisons, but does it really make sense? Is there at least some minor performance impact?</p>
