reduce去重

reduce去重

 let uniarr = uniqObjInArray(this.refIdList);//数组
 let obj = {};
 let peon = uniarr.reduce((cur, next, idx) => {
   console.log('next', obj[next.refId]);
    // obj[next.refId] ? "" : obj[next.refId] = true && cur.push(next)
     if (obj[next.refId] === undefined) {
         obj[next.refId] = true;
        cur.push(next);
     }
     return cur;
 }, []); //设置cur默认类型为数组，并且初始值为空的数组
 

| peon是去重后的数组
