<hr>
<h3 id="splats"><a href="#splats">Splats</a></h3>
<p>A splat argument means that if the argument is an array, you can omit the square brackets and have a variable number of arguments in the method instead.</p>
<p>In the example at the top, this means that <code>m(&quot;div&quot;, {id: &quot;foo&quot;}, [&quot;a&quot;, &quot;b&quot;, &quot;c&quot;])</code> can also be written as <code>m(&quot;div&quot;, {id: &quot;foo&quot;},
