 Imagine that we have a script where for each DOM element found on a page with class "foo" we wish to increment a counter. What's the most efficient way to query for this collection of elements? Well, there are a few different ways this problem could be tackled:</p>

 Use a modern native browser feature such as <code>querySelectorAll()</code> to select all of the elements with the class "foo".</li>
 <li>Use a native feature such as <code>getElementsByClassName()</code> to similarly get back the desired collection. </li>
