我想从两个表中删除相同的值，例如:

var array1 = ["1", "2", "3", "4", "5"]
var array2 = ["3", "4", "5"]

我想要结果:

var result = ["1", "2"]

您可以使用filter()和includes()和concat()。它适用于两个数组

var array1 = ["1", "2", "3", "4", "5"]
var array2 = ["3", "4", "5","6"]

let result = array1.filter(x => !array2.includes(x)).concat(array2.filter(x => !array1.includes(x)))
console.log(result);
