title: V8 native syntax in Chrome
body: <p>Nodejs has special flag <code>--allow-natives-syntax</code>. Is it possible to pass such thing to Google Chrome? Or maybe devtools provide some other way to access such information?</p>
  
  <pre><code>// running node with `--allow-natives-syntax` flag
  
  var obj = { a: true, b: false };
  console.log(%HasFastProperties(obj)); // true (Fast mode)
  delete obj.a;
  console.log(%HasFastProperties(obj)); // false (Dictionary mode)
  </code></pre>
