[Solved] How to display the array?

by


you will require 2 loops, 1 will go through each element of Array3 and Second loop will be used to find the index value will be compared with Array2 to find index of Array 1 and then that index value will be saved in Array4 from Array1

 for (var i = 0; i < Array3.length; i++) 
 {
    var index = Array3[i];
    var position=-1;
    for(var j=0; j < Array2.length;j++)
    {
       if(index==Array2[j])
       {
          position = j;
          break;         
       }
    }
    Array4[i] = Array1[j];
 }
