Js或者Jquery对Json数组进行去重

Question

var arr = [
{"name" : "1","value" : "qqq","age" : "10"},
{"name" : "1","value" : "qqq","age" : "10"},
{"name" : "2","value" : "eee","age" : "20"},
{"name" : "4","value" : "rrr","age" : "50"},
{"name" : "5","value" : "ttt","age" : "100"}
];
除去重复数据，name value age 三个值均相等为重复数据，求大神帮忙

    var arr = [
{ "name": "1", "value": "qqq", "age": "10" },
{ "name": "1", "value": "qqq", "age": "10" },
{ "name": "1", "value": "qqq", "age": "10" },
{ "name": "2", "value": "eee", "age": "20" },
{ "name": "4", "value": "rrr", "age": "50" },
{ "name": "5", "value": "ttt", "age": "100" }
    ];
    for (var i = 0; i < arr.length; i++) {
        for (var j =i+1; j <arr.length; ) {
            if (arr[i].name == arr[j].name && arr[i].value == arr[j].value && arr[i].age == arr[j].age) {
                arr.splice(j, 1);
            }
            else j++;
        }
    }
    console.log(arr)
