React: A Quick Understanding (Deep Dive JumpStart < 2 Hours) udemy course free download

A quick deep dive mini bootcamp - React 19, JSX, Components, Hooks, use, Data Fetching, Suspense, AI and LLM generation

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

I've read all of React's source code, and have given popular talks at React Summit (the world's biggest React conference). Join me in understanding React!
