我正在使用lodash将值数组分组。根据我的代码
_.groupBy(array, a => a.level)
它产生正确的顺序
1.0: [{…}]
1.1: [{…}]
1.1.1: [{…}]
1.1.1.1: [{…}]
1.1.1.1.1: [{…}]

let grouped = _.groupBy(array, a => a.level)
Object.keys(grouped)
如果我使用任何一种转换方法，字典的顺序都会改变。 主要目的是在转换时保留订单。 实际输出为
0: "1.0"
1: "1.1"
2: "1.1.1"
3: "1.1.1.1"
4: "1.1.1.1.1"
5: "1.1.1.1.2"
6: "1.1.1.1.3"
7: "1.1.2"
8: "1.1.2.1"
9: "1.1.3"
10: "1.1.4"
11: "1.1.4.1"
12: "1.1.5"

113: "1.2.14"
。顺序已完全更改，我需要按照字典中的顺序进行操作。
