Most efficient way to set style using pure javascript?
<p>What is the most efficient way to set multiple styling on elements in javascript?</p>

<pre><code>for (i=0;i&lt;=lastSelector;i++) {
var e = mySelector[i],
v = 'opacity 1s';
e.style.WebkitTransition = v;
e.style.MozTransition = v;
e.style.OTransition = v;
e.style.MsTransition = v;
e.style.transition = v;
e.style.opacity = 0;
};
</code></pre>
