根据索引从其他数组中删除数组

Question

我想根据其他数组arr2的索引删除数组arr 。 arr2可以有任何长度。

预计 Output

["test9495","test93992"]

 var arr = ["test234", "test9495", "test234", "test93992", "test234"]; var arr2 = [0, 2, 4]; console.log(arr.splice(arr2,arr2.length)) console.log(arr)

Answer 1

const arr = ["test234", "test9495", "test234", "test93992", "test234"];
const arr2 = [0, 2, 4];
const arr3 = arr.filter((item, index) => arr2.indexOf(index) === -1);
console.log(arr3);
