console.log(factorial(3))// 6
// 阶乘
function factorial(num) 
    if(num <= 1) 
        return 1
    else 
        return num*factorial(num-1)
    


flatten(a: 1, b: c: 2, d: e: 3)
// 遍历对象上的所有属性(待完善...)
function flatten(obj) 
    Object.keys(obj).map((key, i) => 
        console.log(key, obj[key])
        flatten(obj[key])
    )
