title: Remove object item by partial key name
body: <p>I have a javascript object that looks like this:</p>
  <pre><code>{limit: 2, page: 1, filter[description]: 'foo', filter[id]: 1}
  </code></pre>
  <p>I need to remove only items related to the filter and keep it that way:</p>
  <pre><code>{limit: 2, page: 1}
  </code></pre>
  <p>What is the most performative way to perform this procedure?</p>
