Getting started with React

What is React:

• It is a Javascript library used for building user interfaces (UIs), primarily for web applications.

• This helps the developer in building single page applications where the page updates dynamically without refreshing.

When to use react?

• To develop dynamic and interactive UIs like social media feeds, live search.
• Reusable UI components like buttons, forms, cards that can be used again.
• Using react native, we can build mobile apps using the same react knowledge.

Why to use react?

• Fast Performance – Virtual DOM updates only what’s needed, making apps faster.
• Popular & Supported Huge community, lots of libraries.
• Declarative UI – Describe how the UI should look, and React handles updates automatically.
• Easy Maintenance – Component-based architecture keeps code organized and scalable.

How to install react:
• First install Node.js and create a react app using Vite or CRA.

npm create vite@latest my-app
cd my-app
npm install
npm run dev

Enter fullscreen mode Exit fullscreen mode

After run all this commands in terminal, a react project will be created.
