Code inspection notes

Check in the function, the console output result should be before the return result,

[1] The console output result should be before the return return result

[2] After the return, check that the console output is undefined

Example: ItemCount.prototype.get_count = function(good ){
var item_count=_.countBy(this.inputs,function(barcode){
        return barcode.split('-')? barcode:barcode.split('-');
    });
    for(good in item_count){
        if (_.indexOf(good,'-')!=-1){
            item_count[good.split('-')[0]]=good.split('-')[1];
            item_count[good]=undefined ;
        }
    }
     [1] console.log(item_count)==> output normal return result
    return item_count;===> return {"ITEM000001":5,"ITEM000005":3,"ITEM000003":"2" }
     【2】console.log(item_count)==>输出undefined
   }
