how to use .filter to get the same element thats in two arrays code example

Example 1: javascript filter array of objects by array

var arr = [1,2,3,4],
    brr = [2,4],
    res = arr.filter(f => !brr.includes(f));
console.log(res);

Example 2: filter an array of objects and match its key with values inside another array

const arr = [1, 2, 3, 4]
const brr = [2, 4]
const res = arr.filter((f) => !brr.includes(f))
console.log(res)
