Begin with the mechanism
React is easier when render, identity, state, and effects are concrete operations instead of slogans.
React from the
first render onward.
ReactBook is a connected guide to the model underneath modern React, from the first root and render to identity, state, effects, tooling, and production work.
Volume I is completely free. No account or card required.
RenderIdentityStateEffectsTooling
React makes more sense when you stop memorizing APIs and start following the work.
Build a mental model you can use to explain rerenders, stale state, remounts, race conditions, effect cleanup, and the behavior of a real application.
One complete path through the fundamentals
See every lesson01
The first React screen
Start with the browser, createRoot, the root container, elements, and your first component.
02Components before abstractions
Learn component identity, files, props, children, composition, and conditional UI.
03JSX in real React code
Work through expressions, attributes, arrays, fragments, list keys, and the JavaScript around components.
04State and events from scratch
See how handlers, state snapshots, queued updates, forms, and derived UI actually fit together.
05Tooling and the first milestone
Use Vite, TypeScript, React DevTools, production builds, and a complete project review.
Read the model. Then prove you can use it.
Keep one line of reasoning
Each lesson builds on the last, so the details form a model instead of a collection of unrelated tips.
Keep the model close
