说我有
arr1 = ["Tom","Harry","Patrick"]
arr2 = ["Miguel","Harry","Patrick","Felipe","Mario","Tom"]
如何删除数组中的重复元素？
我想要这个输出
arr2 = ["Miguel","Felipe","Mario"]
最佳答案
使用 filter 结合 includes。示例:
let arr1 = ["Tom","Harry","Patrick"]
let arr2 = ["Miguel","Harry","Patrick","Felipe","Mario","Tom"]
arr2 = arr2.filter(x=>!arr1.includes(x))
console.log(arr2)关于javascript - 如何以 Angular 删除 2 个数组之间的重复元素？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/52194139/
