Today, we are going to embark on a journey to this star and uncover the powers it holds: its component-based architecture.

React is a Javascript library for building user interfaces, and it was created by a team at Facebook.

Its claim to fame has been the simplicity, speed, and scalability it provides in the creation of complex applications.

Imagine a construction set. You get individual bricks, and you combine them to create structures. We call these bricks “components”.

Understanding Components

Let’s think about a web page for a moment. Almost every web page we see on the internet is made up of smaller, reusable pieces.

For example, a header, a footer, a sidebar, and a main content area.

These pieces can be considered as components.

Each component in React is an independent, reusable piece of code that controls a part of the UI.
