Thinking in React: A Step-by-Step Tutorial Reference
This is a concise, revisit-friendly guide based on the official "Thinking in React" tutorial. It is written for JavaScript learners who want a structured React tutorial. The goal is to build predictable component hierarchies and state design.
1) Start with a Mock
Begin with a static UI mock. Focus on structure, not behavior.
2) Break the UI into Components
Identify natural boundaries (cards, rows, lists, panels). Each component should have a single responsibility.
3) Build a Static Version First
Implement the UI with props only. No state. No effects.
4) Find the Minimal State
Only store the data that changes over time and cannot be derived. Everything else should be computed from props or state.
5) Decide Where State Lives
Lift state to the closest common ancestor that needs it. Pass it down via props.
6) Add Inverse Data Flow
Let child components update state via callbacks passed from parents.
7) Practical Checklist
- Components are small and focused.
- State is minimal and colocated.
- Props are the primary data flow.
- Derived values are computed, not stored.
