如何从javascript中第二个数组中存在的数组中删除元素？ [复制]

Question

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

我需要做一些事情，从 arr1 中删除“b”和“d”。当然，我还需要从 arr1 中删除 arr2 中存在的元素。

Answer 1

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);
