title: Remove list of keys in object, the key may not exist
body: <p>I have a object that <em>may</em> have some keys</p>
  <pre><code>const input = {
    whatsapp: &quot;123&quot;,
    telegram: &quot;bbb&quot;,
  }
  </code></pre>
  <p>And I want to remove a list of <strong>possible</strong> keys:</p>
  <pre><code>const removeThis = ['whatsapp', 'telegram', 'signal', 'wechat']
  </code></pre>
  <p>Using Ramda, how can I remove all possible keys in the object <code>input</code>?</p>
  <p>The key may not exist in the object.</p>
