What does this javascript syntax mean ? (0, _parseKey2.default)(something) : <p>I find this notation everywhere in Webpack generated libs but I don't understand it :</p>

<pre><code>var a = (0, _parseKey2.default)(something)
</code></pre>

<p>What does the <code>(0, _parseKey2.default)</code> stands for ? I don't remember seeing those coma separated expressions between parenthesis elsewhere that in function parameters, so maybe I am just missing something simple.</p>

<p>Thanks for your help.</p>
