javascript - 如何在Javascript中从二维数组中过滤重复的整数和字符串子数组

Question

我收到一个由整数和字符串组成的二维数组，我想从中删除重复项:

原始数组 = [["admin", 2, "regular"], ["customer", "regular"], ["regular", "customer"], [1], ,["admin "], [1], ["管理员"]

预期结果 = [["admin", 2, "regular"], ["customer", "regular"], [1], ["admin"]]

请问我怎样才能用 Javascript 做到这一点？

如果你的数组(及其子数组)被重新排序，这有关系吗？如果没有，那么:

var array = [["admin", 2, "regular"], ["customer", "regular"], ["regular", "customer"], [1],["admin"], [1], ["admin"]];

array = array.map(x => x.sort()).sort();

var uniqueArray = [];
uniqueArray.push(array[0]);

for (var i = 1; i < array.length; i++){
  if (JSON.stringify(array[i]) != JSON.stringify(array[i-1])){
      uniqueArray.push(array[i]);
      }
}

console.log(uniqueArray);
