bucketSort

Sorts an array of numbers, using the bucket sort algorithm.

• Use Math.min(), Math.max() and the spread operator (...) to find the minimum and maximum values of the given array.
• Use Array.from() and Math.floor() to create the appropriate number of buckets (empty arrays).
• Use Array.prototype.forEach() to populate each bucket with the appropriate elements from the array.
• Use Array.prototype.reduce(), the spread operator (...) and Array.prototype.sort() to sort each bucket and append it to the result.

const bucketSort = (arr, size = 5) => {
  const min = Math.min(...arr);
  const max = Math.max(...arr);
  const buckets = Array.from(
    { length: Math.floor((max - min) / size) + 1 },
    () => []
  );
  arr.forEach(val => {
    buckets[Math.floor((val - min) / size)].push(val);
  });
  return buckets.reduce((acc, b) => [...acc, ...b.sort((a, b) => a - b)], []);
};

bucketSort([6, 3, 4, 1]); // [1, 3, 4, 6]
