So, we decided to pen a dedicated article that addresses these common queries. In this piece, we’ll dive deep and show why using NodeJS with React is a smart move. But before we delve into the meat of the matter, let’s start at square one and lay the foundation.

Understanding ReactJS

Explanation of What ReactJS is

ReactJS is a popular JavaScript library used to build user interfaces, particularly web apps. It allows developers to create reusable UI components and efficiently manage the app’s state. Think of ReactJS as the building blocks of your web app, it’s like legos for your code.

How ReactJS Works

ReactJS uses a virtual DOM (Document Object Model) to keep track of changes in the app’s state. When the state of the app changes, ReactJS updates the virtual DOM and then updates the actual DOM only where it’s needed. This approach makes updating the UI faster and more efficient, resulting in a smooth user experience.

Advantages Of Using ReactJS 

Statista states that in 2022, NodeJS surpassed ReactJS as the most utilized web framework among software developers globally.
