香草JavaScript：如何搜索对象数组，关键是数组

我有一个对象数组。 每个对象都是

{key，value}

对于每个对象键，都是一个由字符串组成的数组

['foo'，'bar'，'baz']

。 我想从数组中删除任何重复的

['foo'，'bar'，'baz']

，以便只对唯一值进行进一步处理

目前我正在做这件事

function removeArrayDupes(input){
var i = input.length;
var previous;
input.sort();

 if (i){
        while (--i){
            var cur = input[i];
            if (!cur.key){
                // Remove empty records
                input.splice(i,1);
            } else {
                // Clear duplicates
                if ((previous) && (input[i].key) === previous){
                    input.splice(i,1);
                    regex= "/" + JSON.stringify(input[i].key) + "/g";
                    previous = input[i].key;
                } else {
                    previous = input[i].key;
                }
            }
        }
    }
}

我的问题是：如果副本数小于3，则不会删除单个副本

我的大脑很累，因为我看不出我把事情搞砸了

我可以多花一两个脑子来解决这个问题

我正在寻找使用香草JavaScript的解决方案。这不仅仅是为了让它发挥作用< 我想了解这个问题，以及是否有更好的算法

样本数据：

[
{key: ["foo","bar","baz"], value: "Some data"},
{key: ["foo","bar","baz"], value: "Some data"},
{key: ["foo","bar","baz"], value: "Some data"},
{key: ["baz","bar","foo"], value: "Some data"},
{key: ["bar","foo","baz"], value: "Some data"},
{key: ["bar","foo","bar"], value: "Some data"},
{key: ["bar","foo","bar"], value: "Some data"},
{key: ["bar","foo","bar"], value: "Some data"},
{key: ["bar","foo","bar"], value: "Some data"},
{key: ["baz","bar","foo"], value: "Some data"},
{key: ["baz","bar","foo"], value: "Some data"},
]

期望输出：

[
{key: ["foo","bar","baz"], value: "Some data"},
{key: ["baz","bar","foo"], value: "Some data"},
{key: ["bar","foo","baz"], value: "Some data"},
{key: ["bar","foo","bar"], value: "Some data"},
{key: ["baz","bar","foo"], value: "Some data"}
]

你能添加一个数据样本和预期结果吗？
