title: Merge two objects and overwrite the values if conflict
body: <p>I'm trying to merge two objects and overwrite the values in the process.</p>
  
  <p>Is it possible with <a href="http://underscorejs.org/" rel="noreferrer">underscore</a> to do the following? (I'm fine with not using underscore I just want it to be simple)</p>
  
  <pre><code>var obj1 = {
      "hello":"xxx"
      "win":"xxx"
  };
  
  var obj2 = {
      "hello":"zzz"
  };
  
  var obj3 = merge(obj1, obj2);
  
  /*
  
  {
      "hello":"zzz",
      "win":"xxx"
  }
  
  */
  </code></pre>
