title: JavaScript - Return differences between two Objects?
body: <p>Can someone show me how to return the new data when comparing something like this. using vanilla JavaScript.</p>
  
  <pre><code>{
      "48": "{\"sid\":\"48\",\"name\":\"title 1\"}",
      "77": "{\"sid\":\"77\",\"name\":\"The blahblah title\"}"
  }
  </code></pre>
  
  <p>compared to this</p>
  
  <pre><code>{
      "48": "{\"sid\":\"48\",\"name\":\"title 1\"}",
      "77": "{\"sid\":\"77\",\"name\":\"The blahblah title\"}",
      "83": "{\"sid\":\"83\",\"name\":\"The blahblah derp\"}",
      "87": "{\"sid\":\"87\",\"name\":\"The derpy title 4\"}"
  }
  </code></pre>
  
  <p>it should return only the differences.</p>
  
  <pre><code>{
      "83": "{\"sid\":\"83\",\"name\":\"The blahblah derp\"}",
      "87": "{\"sid\":\"87\",\"name\":\"The derpy title 4\"}"
  }
  </code></pre>
