{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:"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},{})
