title: Check if checkbox is checked in ANGULAR 10
body: <p>Given this checkbox:</p>
  <pre><code>&lt;input type=&quot;checkbox&quot; name=&quot;sendemail&quot;&gt;
  </code></pre>
  <p>How can I check if its checked or not in Angular 10?</p>
  <p>I've found many examples but they look too complex just for checking a value.</p>
  <p>Thanks.</p>
