// A sequência começa com 0 e 1, depois,
// os números subsequentes são compostos
// pela soma dos dois números anteriores
// da sequência. Daí:
// (x - 2) + (x - 1) = próximo número da sequência
function fibonacci(n) {
const list = [0, 1];
for (let x = 2; x < n + 1; x += 1) {
list.push(list[x - 2] + list[x - 1]);
}
