Why don't you use an object? It looks like you're trying to model a set. This wont preserve the order, however.

var set1 = {"Vijendra":true, "Singh":true}
var set2 = {"Singh":true,  "Shakya":true}

// Merge second object into first
function merge(set1, set2){
  for (var key in set2){
    if (set2.hasOwnProperty(key))
      set1[key] = set2[key]
  }
  return set1
}

merge(set1, set2)

// Create set from array
function setify(array){
  var result = {}
  for (var item in array){
    if (array.hasOwnProperty(item))
      result[array[item]] = true
  }
  return result
}
