About this course

Struggling to maintain large, complex React applications? Efficient refactoring and performance tuning are critical skills for any modern frontend developer. This course provides the foundational knowledge and practical strategies needed to systematically improve the structure and speed of your React projects, leveraging the efficiency gains provided by modern AI coding assistants. What you'll learn: * Understand core architectural principles, including modularity and separation of concerns, for scalable React components. * Apply refactoring patterns to convert legacy component structures to modern functional components and hooks. * Diagnose common performance bottlenecks using built-in developer tools and interpret performance metrics. * Implement optimization techniques like memoization, code splitting, and lazy loading to reduce initial bundle size. * Practice using AI coding assistants effectively to suggest structural improvements and automate repetitive boilerplate code. * Configure component testing basics to ensure architectural changes do not introduce regressions. We start with foundational definitions of technical debt and modular design before moving into practical performance analysis and advanced refactoring exercises. The course emphasizes reading and understanding code transformation patterns. This course is designed for beginner and intermediate developers familiar with basic JavaScript and React syntax who want to professionalize their code quality. No prior experience with large-scale refactoring or performance tuning is required. Start improving your React codebase health today.
