A naive implementation of bucket sort

bucketsort.js

function bucketSort(arrToSort) {
	const buckets = {}

	for (let num of arrToSort) {
		buckets[num] = buckets[num] ?? [];
		buckets[num].push(num);
	}

	let newArr = []
	for (let i of Object.keys(buckets)) {
		newArr = newArr.concat(buckets[i])
	}

	return newArr;
}
