Mastering Data Structures and Sorting Algorithms in JavaScript

Quicksort (Implementation)

Explore how to implement the quicksort sorting algorithm in JavaScript. Understand using the Hoare partition scheme to choose pivots, swap elements, and recursively sort subarrays for efficient array sorting.

We'll cover the following...

First, we create a function that receives the array we want to sort as an argument. It should also be able to get the left and right value. However, as we don’t pass these values at the beginning, it should have a default value as well.

Node.js
function quicksort(array, left, right) {
   left = left || 0;
   right = right || array.length - 1;
}

Next, we need to create a function that chooses the pivot. In this example, I use the ...
