Requirements

• Have experience with React (1-2 years)
• Ability to build applications with React

Description

You've been working with React for a while, building applications and following best practices. But do you sometimes find React behaving in ways you don’t fully understand? Do unexpected re-renders, performance issues, or complex component interactions leave you feeling stuck?

This course is designed to take you beyond the fundamentals and into the advanced mechanics of React. We’ll break down the hidden intricacies of React’s rendering engine, performance optimization techniques, and architectural patterns that top React developers use to build scalable and efficient applications.
What You’ll Learn:

- Understanding React State Like Never Before: Learn exactly how React manages state, how it triggers updates, and how to avoid common state-related pitfalls.

- Deep Understanding of Re-Rendering: Understand what re-rendering truly means, when React decides to re-render a component, and how to prevent unnecessary renders.

- React’s Decision Process: Mount, Re-Render, and Unmount: Gain a crystal-clear understanding of when React mounts a component, when it re-renders, and when it unmounts—and how you can control this behavior for better performance.

- Memoization & Performance Optimization: Master techniques like useMemo, useCallback, and React.memo to optimize expensive computations and prevent unnecessary updates.

- Reconciliation & Diffing Algorithm: Learn how React efficiently updates the DOM behind the scenes and how understanding this process can help you write more performant components.

- Higher-Order Components (HOC): Explore how to enhance component functionality using HOCs and compare them with modern alternatives like hooks.

- Context API & Advanced State Management: Dive deep into React’s Context API, fix some performance issue

- useRef & ForwardRef: Learn how to manage references, avoid unnecessary re-renders, and directly manipulate the DOM when needed.

- Handling Race Conditions & Async Pitfalls: Discover how to prevent common issues when dealing with asynchronous operations in React, ensuring a smooth and bug-free user experience.

- How to Optimize Performance in React Applications: Learn real-world techniques to improve app performance, reduce unnecessary renders, and make your React applications faster and more efficient.

By the end of this course, you won’t just use React—you’ll truly understand React. You’ll be able to debug complex issues, optimize performance, and write more maintainable and scalable code with confidence.

Who this course is for:

• React developers who want to improve their skills
• Want to understand React in depth
