Original Answer
function getNthNumber() { const memoize = []; const cb = (n) => { if(n <= 2 ) return 1; if(memoize[n]) return memoize[n]; memoize[n] = cb(n - 1) + cb(n - 2); return memoize[n]; } return cb(n) } getNthNumber()
Candidate Answer
function getNthNumber() { if (n <= 2) return; let prev1 = 1; let prev2 = 1; let current; for (let i = 3; i < n; i++) { current = prev1 + prev2; prev2 = prev1; prev1 = current; } return current; } getNthNumber()
