Introduction

This course is designed for experienced React developers looking to deepen their knowledge of modern React.js development. It covers advanced concepts such as state management, performance optimization, server-side rendering (SSR), micro frontends, testing strategies, and integrating React with GraphQL. By the end of the course, participants will have the skills to build scalable, high-performance, and maintainable enterprise-level applications.

Prerequisites

Participants should have:

• Strong proficiency in JavaScript, ES6+, and TypeScript
• A solid understanding of React fundamentals (components, props, hooks, and context)
• Experience with React Router and API integration
• Familiarity with state management (Redux, Context API, or Zustand)
• Basic knowledge of unit testing and debugging in React
