Question

数组如下所示，怎么统计出inputer最多的三个名字和重复的次数，求一个算法vardata=[{id:"001",inputer:"张三",inputer_code:"003"},{id:"002",inputer:"诺一",inputer_code:"001"},{id:"003",inputer:"张三",inputer_code:"003"},{id:"004",inputer:"诺一",inputer_code:"001"},{id:"005",inputer:"李四",inputer_code:"004"},{id:"006",inputer:"胡六",inputer_code:"001"},{id:"007",inputer:"张三",inputer_code:"003"},{id:"008",inputer:"诺一",inputer_code:"001"},{id:"009",inputer:"王五",inputer_code:"003"},{id:"010",inputer:"王五",inputer_code:"001"},{id:"011",inputer:"李四",inputer_code:"004"},{id:"012",inputer:"诺一",inputer_code:"001"}];谢谢！

Answer 1

data.reduce(function(prev,next){
prev[next.inputer]=(prev[next.inputer]+1)||1;
returnprev;
},{});
                            

Answer 2

次数有了，接下来就简单了
constresult=data.reduce((total,cur)=>{
total[cur.inputer]=total[cur.inputer]?total[cur.inputer]+1:1;
returntotal
},{})
