Tests:

Native
const newSet = newArr.reduce((acc, value) => { acc.set(value, true); return acc; }, new Map()); const oldSet = oldArr.reduce((acc, value) => { acc.set(value, true); return acc; }, new Map()); const diff = newArr.filter(value => !oldSet.has(value));
Lodash.js filter
_.differenceWith(newArr, oldArr, _.isEqual);
