You can merge the arrays Or combine the array so it will automatically do what you want .

If you want to find the unique elements

// Merges both arrays and gets unique items var array3 = **

arrayUnique(array1.concat(array2));

function arrayUnique(array) {
   var a = array.concat(); 
   for(var i=0; i
