How to study React to become a pro. Introduction to React.

React has the largest market share among JavaScript frameworks — but many developers struggle to learn it effectively.

In this presentation, I share a clear roadmap to mastering React based on my experience as a front-end engineer. You'll learn how to understand components, handle state, and utilize the virtual DOM to build fast, maintainable SPAs.

Perfect for developers who want to move from tutorials to professional-level understanding of React.

1. How to Study React to Become a Pro Introduction to React.
2. Why React Dominates the Market Market Leader Strategic Learning Following a structured roadmap is essential for success High Learning Curve React has the largest market share among JavaScript frameworks worldwide Despite popularity, React has a high failure rate for beginners
3. React Powers Single Page Applications What is SPA? • • • • Screen transitions without server response delays Lightning-fast user experience Replaces content below the body tag in HTML Only display parts change, not entire page SPA technology enables quick screen transitions by updating only necessary parts
4. Understanding Components HTML described in JavaScript for component creation React breaks screens into reusable building blocks called components Components nest inside each other through imports Combine components like buttons, headers, and footers 01 JSX Syntax 02 Parent & Child 03 Screen Building
5. The Virtual DOM Advantage Renders only differences Compares before and after Virtual DOM stores screen data React updates only the parts affected by data changes, not the entire screen Update UI Before State Detect Changes
6. State and Props: The Foundation State Each component holds its own data using useState UI Updates State changes trigger virtual DOM to update display Props Pass state from parent components to child components
7. Advanced State Management Props Basic parent-to-child data flow Share state across component tree Pro Tip: Build a JavaScript todo list before learning React to understand state management fundamentals Global state management for complex apps 1 2 3 Context API Redux As applications grow, React offers powerful tools for managing complex state
8. State Management is Everything Understanding how data flows and triggers UI changes is the key to React mastery
9. Four Keys to Learning React 1 SPA Framework Master single page application architecture 3 Virtual DOM Understand efficient rendering 4 State Management Control data flow and UI updates 2 Components Build reusable UI building blocks Follow this roadmap systematically, practice with real projects, and you'll become a React pro!
