多次元配列の重複削除【JavaScript】

Question

jsで多次元配列の重複削除について教えていただきたいです。
要素同士が持つidとnameがに同じ値の場合、重複削除して1ペアのみ残したいです。

実現したい内容
var arr = [
{id:111 , name:"aaa" , date:003 , file:004},
{id:111 , name:"bbb" , date:003 , file:004},
{id:222 , name:"aaa" , date:003 , file:004},
{id:222 , name:"bbb" , date:003 , file:004},
{id:111 , name:"aaa" , date:003 , file:004},
{id:111 , name:"aaa" , date:003 , file:004},
{id:333 , name:"ccc" , date:003 , file:004},
{id:222 , name:"bbb" , date:003 , file:004},
]

↓ 〜重複削除〜

var arr = [
{id:111 , name:"aaa" , date:003 , file:004},
{id:111 , name:"bbb" , date:003 , file:004},
{id:222 , name:"aaa" , date:003 , file:004},
{id:222 , name:"bbb" , date:003 , file:004},
{id:333 , name:"ccc" , date:003 , file:004},
]

分かりづらくて申し訳ありませんが、ご教示のほどよろしくお願いいたします。

Answer 1

そもそも多次元配列の表記がおかしいですが

var arr = [
{id:111 , name:"aaa" , date:"003" , file:"004"},
{id:111 , name:"bbb" , date:"003" , file:"004"},
{id:222 , name:"aaa" , date:"003" , file:"004"},
{id:222 , name:"bbb" , date:"003" , file:"004"},
{id:111 , name:"aaa" , date:"003" , file:"004"},
{id:111 , name:"aaa" , date:"003" , file:"004"},
{id:333 , name:"ccc" , date:"003" , file:"004"},
{id:222 , name:"bbb" , date:"003" , file:"004"},
];
arr=[...new Set(arr.map(JSON.stringify))].map(JSON.parse);
console.log(arr);
