对于以下fibonacci函数,它按预期工作:
function fibonacci(n) {
var nums = []
var a = b = 1
for (let i = 0; i < n; i++) {
[a, b] = [b, a + b]
nums.push(a)
}
return nums
}
console.log(fibonacci(5));
// outputs: [1,2,3,5,8]但在我更改了两个语句的顺序后,它不起作用:
function fibonacci(n) {
var nums = []
var a = b = 1
for (let i = 0; i < n; i++) {
nums.push(a)
[a, b] = [b, a + b]
}
return nums
}
console.log(fibonacci(5));
// outputs: [1,1,1,1,1] …
