if(arr.length%2 != 0){
    //odd case

    //find middle index

const median = arr => {
  const mid = Math.floor(arr.length / 2),
    nums = [...arr].sort((a, b) => a - b);
  return arr.length % 2 !== 0 ? nums[mid] : (nums[mid - 1] + nums[mid]) / 2;
};
console.log(median([5, 6, 50, 1, -5]));
console.log(median([1, 2, 3, 4, 5]));
