javascript - 打印最后两个斐波那契数的副本

Question

我正在尝试打印最多为 n 的斐波那契数列。出于某种原因，下面的代码将最后一个数字打印了两次，请帮忙。

function fibonacci(n) {
  let i;
  const fib = [];

  fib[0] = 0;
  fib[1] = 1;

  for (i=2; i<n; i++) {
    fib[i] = fib[i-2] + fib[i-1];
    fib.push(fib[i]);
  }
  console.log( fib );
}

您需要在索引处分配值或推送总和。

function fibonacci(n) {
    let i;
    const fib = [];

    fib[0] = 0;
    fib[1] = 1;

    for (i = 2; i < n; i++) {
        fib[i] = fib[i - 2] + fib[i - 1]; // either this assignm. or the next line only
        // fib.push(fib[i - 2] + fib[i - 1]);
    }
    return fib;
}

console.log(fibonacci(8));
