javascript - 如何从javascript中第二个数组中存在的数组中删除元素？

Question

const arr1 = ["a", "b", "c", "d", "e"];
const arr2 = ["b", "d"];

我需要做一些从 arr1 中删除“b”和“d”的事情。当然，我需要从 arr1 中删除也存在于 arr2 中的元素。

尝试使用filter+ includes：

const arr1 = ["a", "b", "c", "d", "e"];
const arr2 = ["b", "d"];

let result = arr1.filter(el => !arr2.includes(el));
console.log(result);
