como usar o median no javascript es6

Returns the median of an array of numbers.

Find the middle of the array, use Array.prototype.sort() to sort the values. Return the number at the midpoint if length is odd, otherwise the average of the two middle numbers.

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;
};

median([5, 6, 50, 1, -5]); // 5
