This week was mainly focused on deepening my understanding of Context API and useReducer, but this time not just through theory or small examples — I implemented these concepts inside real projects.
Most of my learning this week happened inside my WorldWise project, where I practiced advanced state management and application architecture.
Instead of just watching tutorials, I tried to apply every concept directly into a real codebase.
That made a huge difference.
Practicing Context API in a Real Project
This week I continued working with Context API, but this time at a deeper level.
I used Context API inside the WorldWise project to manage application state and share data between components without prop drilling.
Working inside a real project helped me understand:
- How Context Provider should be structured
- Where Context should live in the app
- How to keep Context clean and organized
- How to avoid unnecessary complexity
This felt very different from small demo projects.
Inside a real application, you start to understand why Context API exists.
useReducer in Real Applications
I also continued practicing useReducer, especially in situations where state logic becomes complex.
Using useReducer helped me manage structured state logic instead of using many useState hooks.
This improved:
- Code organization
- State predictability
- Debugging
- Application logic clarity
I now feel much more confident using useReducer together with Context API, which is a powerful combination for medium-sized React apps.
Fake Authentication System
Another important concept this week was Authentication using a Fake Auth system.
I implemented a simple authentication flow to understand:
- How login state works
- How protected areas of the app work
- How authentication affects navigation
- How React apps control user access
This was not a real backend authentication system, but it helped me understand how authentication works conceptually in React applications.
This knowledge will be very useful when I implement real authentication later.
Coding Challenge — Improving My React Quiz App
Alongside the WorldWise project, I also completed a coding challenge where I improved my previous React Quiz Application.
In this challenge, I:
- Replaced prop-based state management with Context API
- Used useReducer inside Context
- Centralized application state
- Improved the code structure
- Made the state logic cleaner
This helped me understand how to refactor an existing project into a better architecture.
This was not about building a new project — it was about improving an existing codebase, which is a very important real-world skill.
Real Learning Happened Through Practice
This week confirmed something important for me:
Learning React is not just about knowing hooks.
Real understanding comes from:
- Implementing concepts in projects
- Improving old code
- Refactoring architecture
- Solving real problems
Most of this week’s learning happened inside the WorldWise project, where I practiced real application patterns.
Next Focus — React Performance Optimization
Next, I will move toward React Performance Optimization.
This will include concepts like:
Avoiding unnecessary re-renders
Memoization techniques
Component optimization
Understanding React rendering behavior
Hooks like:
useMemo
useCallback
React.memo
Right now I only know their names, but the goal is to deeply understand how performance optimization works, not just use the hooks blindly.
After that, I will apply these concepts inside my real projects like WorldWise.
This week felt like another step toward thinking more like a real React developer instead of just a learner.
