Introduction

React is a JavaScript library for building user interfaces. It is maintained by Facebook and a community of individual developers and companies.

It uses a component-based architecture that helps us build complex UIs from small and isolated pieces of code called "components", following a declarative approach. This makes the code easier to understand and maintain, allowing us to build more robust and complex applications.

Why React?

React is the most popular JavaScript library among frontend developers. It has a growing ecosystem and a strong developer community that makes it easy to find solutions for most problems.

It is also used by many companies, including Facebook, Instagram, Vercel and many more.

This, plus the fact that it is open source, free to use and has an amazing developer experience, makes React a no brainer for most frontend projects.
