Continuing Redux Toolkit – Getting Hands-On (Day-12)

 

Catching Up with Redux Toolkit – Making Things Click

After yesterday's deep dive into the theory of Redux Toolkit, today was all about filling in the gaps and getting some hands-on practice.

Some tasks were left unfinished yesterday — especially around practical implementation — so I focused on applying what I learned by setting up a Redux Toolkit-powered app from scratch.

What I Did Today:

 Redux Toolkit Implementation:

  • Revisited configureStore() and understood how to register multiple slices

  • Implemented a working counter slice using createSlice()

  • Practiced dispatching actions like increment, decrement, and reset

  • Connected Redux state with UI using useSelector

  • Created a separate slice for a dummy user list to simulate real-world structure

 Folder Structure & Best Practices:

  • Organized the Redux files into folders: /store, /features, /slices

  • Learned about keeping slice logic clean and separating concerns

Key Learnings:

  • The createSlice() API really simplifies managing state logic in one file

  • Middleware like Redux DevTools helps in tracking actions and debugging

  • Multiple slices can be combined inside configureStore() as separate reducers

  • Using Selector and Dispatch properly ensures a smooth and clean data flow between components

 A Challenge I Faced:

How to manage multiple slices and use their state separately in different components?

At first, I was confused about how slices would interact and how useSelector would know which one to access. After re-reading the Redux Toolkit docs and testing manually, I realized that each slice is mapped to a unique key in the store, which is then accessed like:

 Gracias:

I’m thankful for the extra day to catch up — and honestly, that pause helped reinforce my learning.

Revising GitHub CLI commands (Day1)

GitHub CLI Revision Today I marked the beginning of my revision journey, and I started with GitHub CLI.  I revised all the commands using GitHub Docs and Git Cheat Sheet. Also I revised from GeeksforGeeks also.  Practiced some basic core commands like:  git init, git clone git add, git commit  git push, git pull  git branch, git merge, git checkout Also Created a test repo and tried to pushed the commits using CLI.  I read full explanations from GeeksforGeeks.  Git Workflow -  Also understand how git workflow-> from staging area, working directory.  GitHub also helps in versioning controlling  Challenges -  Sometimes, merge conflicts led to minor confusions like head and current change but exploring little more from Chatgpt and documentation helps in figuring it out.  Gracias- Grateful to have a mentor for guiding me  I'm thankful for this opportunity to revise more and understanding this concept more in a better way ab...

JavaScript Deep Dive + React Review (Day-5)

 JavaScript & React – Interview Prep Mode Today was all about preparing for frontend interviews , and I focused heavily on reviewing core JavaScript and React concepts from the shared 150+ question set. What I Covered: JavaScript Topics: Completed all JS questions from the set Focused particularly on: Promises & Callback functions Closures and how they work under the hood Async/Await and handling asynchronous logic These topics were a bit tricky at times, but revisiting them helped me gain more confidence and clarity. React Topics (Partially Covered): Reviewed around 90 questions Focused on core concepts: useState , useEffect , useMemo Type-related questions and common hook usage I still need to complete the remaining React questions, but the progress so far has been good i learnt more about these topics than i knew before.  What I Learned: Revisited how closures work and why they’re important in functional JS. Understood as...
