title: Select only specific properties from an array of objects
body: <p>Let's  say I create object like this:</p>
  
  <pre><code>updates.push({
        id: this.ids[i],
        point: point,
        value: value
      });
  </code></pre>
  
  <p>Later on I want to use <code>JSON.stringify</code> on <code>updates</code> object, however I need only
  <code>point</code> and <code>value</code>  like:</p>
  
  <pre><code>updates[{point: 1, value: 12}, {point: 2, value: 24}]
  </code></pre>
  
  <p>What's the best ES6 solution for that?</p>
  
  <p>I looked at some examples with delete, but that's not what I actually need, as I do not want to delete ids.</p>
