自己手写了一个，写的比较粗糙，但是可以看一下~有哪位大神可以提供更优化的写法？

var a=[{name:"May",age:12,id:1},{name:"Jone",age:13,id:5},{name:"May",age:15,id:6}];
        function createNewArray ( arr ){
            var nameTempArr = [];
            var newArr = [];
            for (var i = 0; i < arr.length; i++ ){
                if (nameTempArr.indexOf(arr[i].name) == -1 ){
                    nameTempArr.push(arr[i].name);
                    var obj = {};
                    obj.name = arr[i].name;
                    obj.list = [];
                    obj.list.push(arr[i]);
                    newArr.push(obj);
                }else{
                    //遍历newArr中的数 添加进去
                    for( var j = 0; j < newArr.length; j++ ){
                        if( arr[i].name == newArr[j].name ){
                            newArr[j].list.push(arr[i].name);
                        }
                    }
                }
            }

            return newArr;
        }
