js 对 对象中的各个属性进行操作，并返回新对象

 

 

 

{
    a:100,
    b:1000,
}

将对象中每个属性除以100

 

        const monthFree={
          a:100,
          b:1000
        }
    
        const final = {};

        Object.entries(monthFree).forEach(([key, value]) => {
          final[key] = value / 100;
        });        

        const monthFree={
          a:100,
          b:1000
        }
        const final= Object.entries(monthFree)
          .reduce((acc, [key, value]) => {
            acc[key] = value / 100;
            return acc;
          }, {});
