斐波那契数列

看了python 官网的生成斐波那契数列 示例，于是想使用JavaScript 试试。

python 生成斐波那契数列

# Python 3: Fibonacci series up to n
>>> def fib(n):
>>>     a, b = 0, 1
>>>     while a < n:
>>>         print(a, end=' ')
>>>         a, b = b, a+b
>>>     print()
>>> fib(1000)
0 1 1 2 3 5 8 13 21 34 55 89 144 233 377 610 987

python中a, b = a, a + b这条语句是如何执行的？

javascript 生成斐波那契数列, 5000 以内

[1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, 1597, 2584, 4181]

let a = 1;
let b = 1;
let arr = [];
while(a<5000){
    arr.push(a);
    arr.push(b);
    a = a+b;
    b = a+b;
};
console.log(arr);

javascript 生成斐波那契数列,第 100 个值是什么

function getFbli(n){
    let a = 1;
    let b = 1;
    let i = 1;
    while(i<=n){
        if(i==n){
            console.log(a);
        }
        i = i+1;
        if(i==n){
            console.log(b);
        }
        i = i+1;
        a = a+b;
        b = a+b;
    };
};

getFbli(100) // 354224848179262000000
