body: <pre><code>     var name = [ {
   firstN: 'Dave',
   lastN: 'Mike',
   fullName: 'Dave Mike
   },
   { 
   firstN: 'Dave',
   lastN: 'Pence',
   fullName: 'Dave Pence'
   },
    { 
   firstN: 'Tom',
   lastN: 'Pence',
   fullName: 'Tom Pence'
   }, { 
   firstN: 'Meagher',
   lastN: 'Pence',
   fullName: 'Meagher Pence'
   }, { 
   firstN: 'Surv',
   lastN: 'dyal',
   fullName: 'Surv dyal
   }
    ................and so on like 100s
   ]
  </code></pre>
  
  <p>So I want to find unique names so that names occur only once </p>
  
  <p>So my answer from above data sample should be Dave Mike and Surv Dyal</p>
  
  <p>For this I have gotten only this far</p>
  
  <pre><code>var list =Object.keys(newList).map( function(key){
  
      var temp_firstName = newList[key].firstName + ','+ key;
      var temp_lastName = newList[key].lastName + ','+ key;
      console.log( temp_lastName,temp_firstName );
  
      return temp_lastName, temp_firstName;
  });
  
  console.log(list);
  //console.log(newList);
  </code></pre>
  
  <p>}</p>
