Question

我基本上想做的是，我有多个json对象，根据日期数据，我必须以数组的形式对数据进行分组，使日期成为关键。

Answer 1

It can be done using few lodash function. The code is below `

 var temp1 = _.chain(res.data.events)
                    .orderBy('createdAt', 'asc')
                    .groupBy(function(o) {
                        return moment(o.createdAt).format('DD/MM/YYYY')
                    }).value()

`
