我为nodejs应用程序使用车把模板，并且需要按类别对结果值进行分组。跟随是我渲染后的数据。该小组应分为两个级别

  { "manu":"Maruti","Fuel":"petrol","name":"X1","price":"rupees","seats":"6"},{ "manu":"Maruti","name":"F1","seats":"7"},"Fuel":"Disel","name":"E1","seats":"5"},{ "manu":"Toyato","name":"R3","name":"G4","seats":"4"},{ "manu":"Kia","name":"W5","seats":"6"}

-Manu
   -Fuel
      -Name,Price,Seats

result = v1.reduce(function (r,a) {
            r[a.c_group] = r[a.c_group] || [];
            r[a.c_group].push(a);
            return r;
        },Object.create(null));

    console.log(result);
