title: How to extend object properties with other in Scala?
body: <p>I am new to Scala, how to extends one properties value from other object. Like in angular, <code>angular.copy(obj1, obj2);</code></p>
  
  <p>If I have two objects, <code>obj1</code>, <code>obj2</code>, both having the same property names. <code>obj2</code>'s value would be overridden to <code>obj1</code>.</p>
  
  <p>How to achieve this in Scala?</p>
