What you'll learn:
- Build functional React components that accept props and return JSX to create reusable UI building blocks.
- Understand what the Fiber Tree and Reconciliation are
- Write JSX syntax correctly and understand the basic rules for creating component markup that React can render.
- Understand what hooks really are and state hooks in React
- Fetch data using React 19's new use hook and display loading states with Suspense boundaries.
- Instruct an AI to generate React code
Master an accurate React mental model in record time! Don't just copy code. Understand React.
Most React tutorials teach you to type along like a robot. You end up with working code but no real understanding of why it works. When bugs appear, or your faced with challenges you didn't see in the projects you imitated, you're stuck.
This course is different. Build an accurate mental model of React's core concepts so you can debug faster, make better architectural decisions, write clean maintainable code, and direct an LLMproperly to generate React code.
