React is a powerful JavaScript library for building fast, scalable front-end applications. Created by Facebook, it's known for its component-based structure, single-page applications (SPAs), and virtual DOM,enabling efficient UI updates and a seamless user experience.

Why Learn React?

Before React, front-end development struggled with:

• Manual DOM Manipulation: Traditional JavaScript directly modified the DOM, slowing down the performance.
• Complex State Management: Maintaining UI state became messy and hard to debug.
• Tight Coupling in Frameworks: Frameworks like Angular introduced complex two-way data binding that made code harder to manage.

Core Features

• Virtual DOM: React updates only the changed parts of the DOM, resulting in faster rendering.
• One-Way Data Binding: Ensures predictable and easy to debug data flow.
• Component-Based Architecture: Breaks UI into reusable pieces, improving the code reusability and scalability.
