问 题

原始数据

[{
                    "Postcode": "",
                    "WorkSince": null,
                    "FundVolume": 300000000,
                    "Intro": null,
                    "type": "基金从业人员资格证",
                    "url": "Upload/UserCenter/20150303/2015030315252534569105.jpg",
                    "id": 19332
                },
                {
                    "Postcode": "",
                    "WorkSince": null,
                    "FundVolume": 300000000,
                    "Intro": null,
                    "type": "基金从业人员资格证",
                    "url": "Upload/UserCenter/20150303/2015030315252534569105.jpg",
                    "id": 19347
    }]
    

需要的数据：

[{
                    
                    "type": "基金从业人员资格证",
                    "url": "Upload/UserCenter/20150303/2015030315252534569105.jpg",
                    "id": 19332
                },
                {
                 
                    "type": "基金从业人员资格证",
                    "url": "Upload/UserCenter/20150303/2015030315252534569105.jpg",
                    "id": 19347
    }]

解决方案

var data = [{type: 1, url: 1, id: 1, a: 1}];
data.map(({type, url, id}) => {
    return {type, url, id};
});

var data = [{type: 1, url: 1, id: 1, a: 1}];
data.map(({type, url, id}) => ({type, url, id}));

两种写法其实一样，第一个种可读性好点，扩展性也好
