Radix Sort (Implementation)

Explore the step-by-step process of implementing Radix Sort in JavaScript. Understand how to extract digits, use digit buckets, and reorder arrays for efficient sorting based on digit positions.

We'll cover the following...

Radix sort uses both counting sort and bucket sort. To implement radix sort, we need to have a radixSort function that receives the array we want to sort.

Node.js
function radixSort(array) {
}

Right now, we need to store the largest digit of the maximum number in the given array, initialize a digit bucket list where we store the values, and the current index.

Node.js
function radixSort(array) {
  const max = Math.max(...array).toString().length;
  let digitBuckets = [];
  let index = 0;
}

Next, we want to initialize a bucket for every digit that’s possible. Let’s say that we have the array [8, 23, 12223, 901, 2990, 12] that we want to sort. Now, max would be equal to 5, as the length of the maximum ...
