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

有谁知道如何删除包含原始值的数组中的重复项？我遇到了不同的片段，如此
和这个和其他一些但没有特别删除原件节点同时。小心分享一些小片段？ 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

您可以尝试过滤您的数组基于该数组中特定值的出现次数：

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)
