    1. function curry(){
    2.   let args=[];
    3.   args.push(...arguments);
    4.   let my=function(){
    5.     if(arguments.length==0){
    6.       let rlt = 0;
    7.       console.log('args:',args);
    8.       return args.reduce((rlt,now)=>rlt+now,0);
    9.     }else{
    10.       args.push(...arguments);
    11.       return my;
    12.     }
    13.   }
    14.   return my;
