Extension with Vanilla JS — a Reel Counter for Instagram.

Got the core detection and counting logic working, and learned a lot by debugging what actually happens on a real webpage.

@AnchalGupta009 Congrats!

23:07,

Tried a few approaches that failed, then figured out location.pathname + Set could track unique Reels. Also learned how to persist the data using localStorage, JSON.stringify() and JSON.parse().

Lots of trial and error, but it’s working now. 🚀

From doubting my first HTML tags to building a vanilla JS extension that counts reels by manipulating live DOMs... Screenshot shows the counter on the right—just a demo, not live yet.

[Tarun Sen @itstarunsen]

tarted building a Reel Counter browser extension with Vanilla JS.

Today I learned how browser extensions use manifest.json and content scripts to interact with other webpages.

It’s a new layer of JavaScript for me.
Soon I’ll share the working version here.

Took my first step into LeetCode today.

The problems themselves weren't the hardest part - understanding what they were actually asking was.

Solved a few beginner problems and learned more about closures, callbacks, prototypes, forEach(), and accumulator logic along the way.

@riya_mishra007 A degree from a Tier-3 college does matter. What if I were to skip this degree and focus solely on coding?

[Tarun Sen @itstarunsen]

Today I learned how JavaScript .sort() works with a compareFn.

I practiced sorting issues by priority using a priority mapping and understood how:

negative → a before b
positive → b before a
0 → same order

Also learned to sort a copy instead of mutating the original React

[Tarun Sen @itstarunsen]

It's important !

Hey guys, I am doing my BCA from a Tier 3 college, but I really want to focus only on coding. What do you think? Does the degree matter, or can I just build things and learn on my own?

Turned my messy React debugging notes into something I can actually understand.

Got stuck, broke things, rewrote the flow, and finally understood why storing derived data in state was causing so many problems.

Improving my React fundamentals 🧠

Today I focused on understanding, not just coding — working with state, controlled inputs, props, and component communication.

Built a small Issue Tracker to practice along the way.

Built a Student Portal while learning React Router.

Features:
• Nested Routes
• Dynamic Routes (:id)
• useParams()
• Outlet
• 404 Page

[Tarun Sen @itstarunsen]

Need some advice.

If you were learning React today, would you stop for a while and go deeper into JavaScript, or continue learning the React ecosystem?

What worked better for you?

[Tarun Sen @itstarunsen]

Finished React Router today.

Built:
• Nested Routes
• Outlet
• Dynamic Routes (:id)
• useParams()
• 404 Page

I got stuck on nested routing, relative paths, and where child components should render. Fixing each mistake while building the project made everything click.
