In this article, we will explain what the idea behind Insertion Sort is and implement it in JavaScript. Insertion Sort is one of the simpler sorting algorithms. It's highly intuitive, stable, in-place, and of comparison-type. A stable sorting algorithm is an algorithm in which two objects with equal keys appear...

Axios is a Promised-based JavaScript library that is used to send HTTP requests. You can think of it as an alternative to JavaScript's native fetch() function. We will be using features such as Promises, async/await, and other modern JavaScript design patterns in this tutorial. If you'd like to get...

Selection Sort is one of the simpler and more intuitive sorting algorithms. It is an in-place, unstable, comparison algorithm. This means that it transforms the input collection using no auxiliary data structures and that the input is overridden by the output (in-place algorithm). Additionally, during its execution, it only reads...
Bubble Sort, sometimes also referred to as Sinking Sort is one of the most widely known sorting algorithms. It is usually one of the first sorting algorithms that CS students come across due to its simplicity and the fact that it is quite intuitive and easy to translate into code....
Jest is a popular, open-source test framework for JavaScript. We can use Jest to create mocks in our test - objects that replace real objects in our code while it's being tested. In our previous series on unit testing techniques using Sinon.js, we covered how we can use Sinon....

In this tutorial, we are going to take a look at Node's native EventEmitter class. You'll learn about events, what you can do with an EvenEmitter, and how to leverage events in your application. We'll also cover what other native modules extend from the EventEmitter class and some examples to...
In this article, we are going to take a look at how to use the Handlebars template engine with Node.js and Express. We'll cover what template engines are and how Handlebars can be used to create Server Side Rendered (SSR) web applications. We will also discuss how to configure...
A few years back, callbacks were the only way we could achieve asynchronous code execution in JavaScript. There were few problems with callbacks and the most noticeable one was "Callback hell". With ES6, Promises were introduced as a solution to those problems. And finally, the async/await keywords...
