Description
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 LLM properly to generate React code.
What You'll Learn
Components & JSX
What components really are and why they must be "pure"
How JSX works under the hood and why its rules exist
What props are and how they work
Writing semantic, maintainable component markup
Reconciliation and the Fiber Tree
How React works under-the-hood
Where React actually stores information
Hooks
useState: Why immutability matters and how React detects changes
useReducer: When to choose reducers over simple state
Modern Data Fetching
Master React 19's new use hook for clean async code
Understand Suspense boundaries
AI and LLM Prompting
Use your knowledge to properly prompt an AI
Get the best results from an LLM generating React apps
