Fibonacci Sequence with loop and with recursion

fibonacci.js

function fibonacci(num) {
  let count = 1,
    start = 0,
    hold,
    seq = [];

  while (num >= 0) {
    hold = count;
    count = count + start;
    start = hold;
    num--;
    console.log(start);
    seq.push(start);
  }

  return seq;
}






const fibb = num => {
  if (num <= 1) return 1;
  return fibb(num - 1) + fibb(num - 2);
};

console.log(fibb(10));  // 89

The second one is niffy and soft! with recursion .
