Thanks for the video! Why not checking for the presence of "index-1" and "index-2" in the cache?

[inactiveaccount]

when using something like cache = cache || [ ] ... what does this mean?

const fibonacci = (term, sequence) => {
if (sequence.length === term) return sequence[sequence.length - 1];

- 2] + sequence[sequence.length - 1]);

return fibonacci(term, sequence);
};

console.log(fibonacci(364, [0, 1]));
