Description

Introduction
This course focuses on building scalable, maintainable, and high-performance React applications. Participants will learn advanced component architecture, state management, modular design, performance optimization, and best practices for large-scale React projects. The course emphasizes real-world patterns that help teams build applications efficiently.

Prerequisites

• Strong understanding of JavaScript (ES6+)

• Intermediate knowledge of React (components, props, state, lifecycle methods)

• Familiarity with HTML, CSS, and front-end development concepts

• Basic understanding of npm/yarn and React tooling (Create React App, Vite, Webpack)
