difference between two arrays javascript

Question

I've seen more than one question solving this but when applying them it didn't work for me, please help me solve this. I've written my code according to this question

    let difference = selectedStores.filter(selectedStore => {
      alreadySyncedStores.filter(productSyncedStores => {
        console.log('productSyncedStores', productSyncedStores);
        console.log('selectedStore', selectedStore);
        console.log('result ', !productSyncedStores.includes(selectedStore));
        !productSyncedStores.includes(selectedStore)
      })
    });
    console.log('>>difference<<<', difference)

both arrays and console results are reflected in the images below thanks in advance.

expected result is : difference = ['100000000713']

You can use this function to get the desired output

Suppose you have two array arr1 and arr2

var arr1 = ['12', '32', '54'];
var arr2 = ['14', '32', '21'];

function GetDifference(arr1, arr2) {
  var diffArr = [];

  arr1.forEach(function(index, value) {
    if (arr2.indexOf(index) == -1) {
      diffArr.push(index);
    }
  });

  arr2.forEach(function(index, value) {
    if (arr1.indexOf(index) == -1 && diffArr.indexOf(index) == -1) {
      diffArr.push(index);
    }
  });

  return diffArr;
}

console.log(GetDifference(arr1, arr2))

You will get ['12', '54', '14', '21'] as output.
