Question

我正在尝试创建斐波那契发生器。也许smb可以向我解释我如何不能从零开始创建序列，但是起点将根据用户请求（例如序列中的数字5）并且可以前进和后退（也为负）。显示数量也应根据用户要求。

function* fibonacci(number) {

let previous_first = 0, previous_second = 1, next = 1;

while(true) {
    next = previous_first + previous_second;
    previous_first = previous_second;
    previous_second = next;

    yield next;
   }
};

Answer 1

如下所示的结果：

function getFibonnaciSequence(firstNum, secondNum, sequenceCount) {
    let sum = 0;
    let squenceArray = [];
    while(sequenceCount != 0) {
    sum = firstNum + secondNum;
    squenceArray.push(sum);
    firstNum = secondNum;
    secondNum = sum;
    sequenceCount--;
		}
    return squenceArray; 
}

console.log(getFibonnaciSequence(2,5, 10));
