How to access element via dataset attribute directly
<p>Assuming I have following mark up:</p>

<pre><code>&lt;div id="Movie" data-genre="horror"&gt;The Hills Have Eyes&lt;/div&gt;
</code></pre>

<p>I know that I can access that element´s dataset attributes using:</p>

<pre><code>document.getElementById("Movie").dataset.genre
</code></pre>

<p>or</p>

<pre><code>document.getElementById("Movie").getAttribute("data-genre")
</code></pre>

<p>But is there a way to get all elements with the same genre without using any other feature? I am thinking about something like that:</p>

<pre><code>document.getElementsByDataSetKey(key)
</code></pre>
