How to compare two arrays and get unique values

[Hari1]

Hi,

I have 2 arrays. I need to get the users not present in the other array. I am using the below code I am able to get unique users but there are duplicates in it.

var arrCapUsers = ["a","b","c","d","e"];
var arrGrpUsers = ["a","b","c","d","e","f","g","h","i","j","k","l"];
var arrFinal = [];


for(var i=0; i<arrCapUsers.length; i++){
  for(var j=0; j<arrGrpUsers.length; j++){
    if(arrCapUsers[i] != arrGrpUsers[j]){
    arrFinal.push(arrGrpUsers[i])
  	}
  }
}

gs.info("arrFinal:"+arrFinal);

Hi,

what do you mean by Unique?

you can use ArrayUtil class and it has different functions

ArrayUtil - Global

I want the output to be as ["f","g","h","i","j","k","l"] discard ["a","b","c","d","e"] as it is present in both the arrays.

Hi,

then do this ->use diff() method

var arrCapUsers = ["a","b","c","d","e"];
var arrGrpUsers = ["a","b","c","d","e","f","g","h","i","j","k","l"];
var arrFinal = [];

var arrayUtil = new global.ArrayUtil();

arrFinal = arrayUtil.diff(arrGrpUsers,arrCapUsers);

gs.info(arrFinal);

Output:

Hi Hari

on page https://community.servicenow.com/community?id=community_article&sys_id=d5d43229db47d0943daa1ea668961... all required methods of the ArrayUtil class are introduced.

To my mind, you can use diff() and unique() without implementing anything.

Kind regards
