filter unsorted
const result = arr1.filter(el => arr2.includes(el))
lodash intersection unsort
const result = _.intersection(arr1, arr2)
filter sorted
const sortedArr1 = arr1.sort() const sortedArr2 = arr2.sort() const result = sortedArr1.filter(el => sortedArr2.includes(el))
lodash intersection sorted
const sortedArr1 = arr1.sort() const sortedArr2 = arr2.sort() const result = _.intersection(sortedArr1, sortedArr2)
