Programming technologie guide
Learn React
Learn React through prerequisites, core workflows, projects, troubleshooting, and production practices.
Best for
- Component-based browser interfaces
- Interactive single-page application features
- Frontend applications that share state across reusable UI components
Prerequisites
- JavaScript functions, arrays, objects, modules, and async/await
- DOM and browser event fundamentals
- Basic npm and development-server workflows
Learning sequence
Recommended Learning Order
- 1
Stage 1
Components, JSX, props, and rendering
- 2
Stage 2
Events, state, derived values, and controlled forms
- 3
Stage 3
Effects, data fetching, loading/error states, and cleanup
- 4
Stage 4
Context, reducers, routing, and reusable hooks
- 5
Stage 5
Testing, accessibility, performance, and production builds
Study Timeline
6 hours/week
Combine state, forms, effects, routing, and API work.
10 hours/week
Build a tested multi-page frontend with realistic data flows.
Project Progression
Beginner: searchable task or product list
Intermediate: routed API dashboard with forms and error states
Portfolio: tested accessible application with authentication-aware UI and performance checks
Common Mistakes
- Using effects for values that can be calculated during render
- Mutating state directly
- Putting all state at the top of the app
- Learning state libraries before understanding built-in React state and effects
Job-Ready Skills
- Components and state
- Hooks and effects
- Forms and validation
- Routing and API integration
- Testing and accessibility
- Performance and build tooling
Frequently Asked Questions
How much JavaScript should I know before React?
Be comfortable with functions, arrays, objects, modules, destructuring, callbacks, promises, async/await, and browser events before relying on React abstractions.
