JS:删除数组中的重复值，包括原始值 [英] JS: remove duplicate values in array, including the original

问题描述

有谁知道如何删除数组中的重复项，包括原始值?我遇到了不同的片段，例如 this和 this 和其他一些但没有特别是同时删除原始节点.愿意分享一个小片段吗?TIA！

Does anyone know how to remove duplicates in an array including the original value? I came across different snippets like this and this and some others but none in particular is removing the original node at the same time. Care to share a little snippet ? TIA!

示例:

[1, 1, 2, 3, 5, 5] -> [2, 3]

推荐答案

您可以尝试根据数组中特定值的出现次数过滤数组:

You could try filtering your array based on the number of occurrences of a specific value in that array:

var arr = [1, 1, 2, 3, 5, 5]

var res = arr.filter((el, _, arr) => {
      return arr.filter(el2 => el2 === el).length === 1
})

console.log(res)
