title: Node.js : How to enable non strict or ECMASCRIPT3 in V8 engine?
body: <p>I believe V8  underlying Node.js supports strict mode or ES5 by default.</p>
  
  <p>Can we enable non strict or ECMASCRIPT 3 in V8 engine?</p>
  
  <p>almost 100% of ES5 features are available in Chrome (V8) see <a href="http://kangax.github.com/es5-compat-table/" rel="nofollow">compatibility table </a>.</p>
  
  <p>But some developers(including me) are still comfortable with ES3, can we have that option?</p>
