Question

我是一名初学者，试图用while循环解决斐波那契问题，但我对使用while循环或数组没有信心。这绝对是一个糟糕的编码，但有人可以查看并告诉我修复它的方法吗？

/* Each new term in the Fibonacci sequence is generated by adding the 
previous two terms. By starting with 1 and 2, the first 10 terms will 
be:

1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...

By considering the terms in the Fibonacci sequence whose values do not 
exceed four million, find the sum of the even-valued terms.*/

function math() {
    arr values = [1,2];
    var fib = 0;
    var sum = 2;

    while (values[values.length]<4000000) {
        fib = values[values.length] + values[values.length-1];
        values.push(fib);
        if (fib%2===0) {
            sum += fib;
        }
    }
    alert(sum);
}
