title: ES6: Filter data with case insensitive term
body: <p>This is how I filter some <code>data</code> by title value:</p>
  
  <pre><code>data.filter(x =&gt; x.title.includes(term))
  </code></pre>
  
  <p>So data like</p>
  
  <pre><code>Sample one
  Sample Two
  Bla two
  </code></pre>
  
  <p>will be 'reduced' to </p>
  
  <pre><code>Bla two
  </code></pre>
  
  <p>if I'm filtering by <code>two</code>.</p>
  
  <p>But I need to get the filtered result</p>
  
  <pre><code>Sample Two
  Bla two
  </code></pre>
