title: Node 5.10 spread operator not working
body: <p><a href="https://nodejs.org/en/docs/es6/#which-features-ship-with-node-js-by-default-no-runtime-flag-required">According to the docs</a>, the latest node (Node 5+) should support the spread operator by default, like so:</p>
  
  <pre><code>const newObj = {
          ...oldObj,
          newProperty: 1
        }
  </code></pre>
  
  <p>And I have node 5.10.1 installed (e.g. that's what 'node -v' tells me). But I am still getting this error:</p>
  
  <pre><code>c:\[myprojectfolder]&gt;node index.js
  c:\[myprojectfolder]\index.js:21
              ...oldObj,
              ^^^

  <p>What am I missing?</p>
