title: How to remove object by key in Javascript array?
body: <p>I have an array like this one:</p>
  
  <pre><code>[{
    '0': [7]
  }, {
    references: [0]
  }, {
    '1': [8]
  }, {
    references: [9]
  }, {
    '2': [20]
  }, {
    references: [50]
  }]
  </code></pre>
  
  <p>I want to remove all objects containing the <code>reference</code> key. Any suggestions?</p>
