Question

我正在使用lodash对一组对象进行分组：

let people = [{name:'carl',group:'one'}, 
{name:'john',group:'one'}, 
{name:'dean',group:'three'}]
_.groupBy(people,"group");

结果：

one: Array (2 items)
0: Object {group: "one", name: "carl"}
1: Object {group: "one", name: "john"}

three: Array (1 item)
0: Object {group: "three", name: "dean"}

我想要的是组数组长度大于1的对象，以便单独分成另一个数组：

one: Array (1 item)
0: Object {group: "one", name: "carl"}

one: Array (1 item)
0: Object {group: "one", name: "john"}

three: Array (1 item)
0: Object {group: "three", name: "dean"}

最好的方法是什么？

我认为你可以使用“排序”方法

let people = [{name:'carl',group:'one'}, 
 {name:'john',group:'one'}, 
 {name:'dean',group:'three'}];

people.sort(function(a,b){
  return a.name.localeCompare(b.name)
});
