我有一些对象，我想按名称排序 . 我正在使用lodash库并使用_.sortBy（） . 但通过使用此功能，我没有得到适当的响应 .
以下是我的activeUser数组
[ { date: 'Tue Dec 11 2018 00:00:00 GMT+0530 (IST)',
time: '10:30',
user_name: 'Happy Teachers DAy',
profilepic: 'http://192.168.0.109:8000//igXFkPIcNxSlhl0IB6c9iOexn.jpeg',
activeType: 'Group',

isCreatedByTherapist: false,
groupMember: [] },
{ date: 'Tue Dec 11 2018 00:00:00 GMT+0530 (IST)',
time: '16:00',
user_name: 'Practice Group',
profilepic: null,
activeType: 'Group',
_id: '5bc1dce4b9d0faf0271e0ef5',
isCreatedByTherapist: false,
groupMember: [] },

isCreatedByTherapist: false,
groupMember: [] },
{ date: 'Fri Dec 12 2018 05:30:00 GMT+0530 (IST)',
time: '14:00',
user_name: 'GCK',
profilepic: 'http://192.168.0.110:8000/LDS3CpweCSSDDdOfa4lR6rPmn.jpeg',
activeType: 'Individual',
_id: '5ae1691241ce6c991f45b7fc',
isCreatedByTherapist: false,
groupMember: [] },
{ date: 'Fri Dec 11 2018 05:30:00 GMT+0530 (IST)',
time: '16:00',
user_name: 'kaushik',
profilepic: 'http://192.168.0.110:8000/DNAtiR1iiG2jgJWsIH5tpZCwv.jpeg',
activeType: 'Individual',
_id: '5b502b2724f36ada24167083',
isCreatedByTherapist: false,
groupMember: [] } ]
sortedName = _.sortBy（activeUser，['user_name']）;
在sortedName中，我得到以下数组作为响应：

使用你的数据而不做任何"group by"，我确实对数组进行了排序 . 我添加了一个额外的记录，大写字母K，"Kaushik" . 您可以看到此方法首先对大写进行排序，然后对小写进行排序，但数组确实已排序 .
确保您首先获得所需的排序，然后查看任何分组的处理 .
