Tests:

Lodash
const notInArr1 = _.difference(arr2, arr1) const notInArr2 = _.difference(arr1, arr2)
Set & Filter
const arr1Set = new Set(); const arr2Set = new Set(); arr1.forEach(value => arr1Set.add(value)); arr2.forEach(value => arr2Set.add(value)); const notInArr1 = arr2.filter(value => !arr1Set.has(value)); const notInArr2 = arr1.filter(value => !arr2Set.has(value));
