javascript基础题来个人。

某员工入职信息为10000，薪资每年涨幅为5%，计算该员工50年后的薪水为多少.

递归，循环都可以

建议还是自己写，就算写错了最起码你去做了，不然下次你遇到了还是不会

let total = Array.from(Array(50)).reduce((pre,i ) => pre += (pre* 0.05), 10000);
// total = 114673.99785753674

    }
    console.log(mysal(year)); //调用函数mysal
    console.log(Math.pow(1.05, 49) * 10000); //验证
