我正在尝试过滤一组 JSON 对象。我是 JavaScript 的新手，并试图用我曾经使用过的编码语言来完成它。基本上，我想采用以下对象数组。

     var result = [
                                {
                                    date : '2016-11-21',
                                    name: 'Bob',
                                    score: 0.1034947
                                },

                                {
                                    date : '2016-10-21',
                                    name: 'Bill',
                                    score: 0.2081911},

                                {
                                    date : '2016-10-21',
                                    name: 'Mary',
                                    score: 0.234947
                                },
                                {
                                    date : '2016-10-21',
                                    name: 'Bob',
                                    score: 0.1034947
                                },

                                {
                                    date : '2016-11-21',
                                    name: 'Bill',
                                    score: 0.2081911},

                                {
                                    date : '2016-11-21',
                                    name: 'Mary',
                                    score: 0.234947
                                },
                                {
                                    date : '2016-12-21',
                                    name: 'Bob',
                                    score: 0.1034947
                                },

                                {
                                    date : '2016-12-21',
                                    name: 'Bill',
                                    score: 0.2081911},

                                {
                                    date : '2016-12-21',
                                    name: 'Mary',
                                    score: 0.234947
                                }




  ]

然后我想根据对象进行过滤。所以例如。

var selected_Names = ['Bob','Mary']

我只想在这种情况下返回 Bob 和 Mary 的信息。

                                    date : '2016-11-21',
                                    name: 'Bob',
                                    score: 0.1034947
                                },



                                {
                                    date : '2016-10-21',
                                    name: 'Mary',
                                    score: 0.234947
                                },
                                {
                                    date : '2016-10-21',
                                    name: 'Bob',
                                    score: 0.1034947
                                },



                                {
                                    date : '2016-11-21',
                                    name: 'Mary',
                                    score: 0.234947
                                },
                                {
                                    date : '2016-12-21',
                                    name: 'Bob',
                                    score: 0.1034947
                                },



                                {
                                    date : '2016-12-21',
                                    name: 'Mary',
                                    score: 0.234947
                                }

const filterNames = arr => names => arr.filter(e => names.includes(e.name));

const names = ['Bob', 'Mary'];

const res = filterNames(result)(names);

console.log(JSON.stringify(res, null, 2));
