Example 2: javascript fibonacci
function fibonacci(n) {
return n < 1 ? 0
: n <= 2 ? 1
: fibonacci(n - 1) + fibonacci(n - 2);
}
console.log(fibonacci(4));

function fibonacci(n) {
const list = [0, 1];
for (let x = 2; x < n + 1; x += 1) {
list.push(list[x - 2] + list[x - 1]);
}
return list[n];
}
console.log(fibonacci(4));
