Learning React after spending months with vanilla and modern JS.

BCA 2nd year, Jaipur. Building small tools that actually work. This = my learning journal.

Rn: logic-heavy utilities (DOM, APIs, browser storage) → scaling into React.

Following #buildinpublic. Let's connect 🚀

Learned how to build a custom hook today — useCurrency, which fetches live currency exchange rates from a public API.

Built my first real multi-concept project today — a password generator.

Following a video Tutorial btw🥀

Used useState for the values, useCallback to memoize the generator function, useEffect to auto-run it on load + on changes, and useRef to grab the input field directly.

Can anyone tell the difference?

In React — Why does an empty dependency array make this effect run only once, right after the component mounts?

Learned useEffect cleanup functions today.

If your code starts something that keeps running in the background—like a timer and event listener you need to clean it up.
Otherwise Memory leaks waiting to happen.

Learned useEffect today — specifically the dependency array, which feels a little bit tricky at first.

Both work identically. Which one do you prefer?

Not for Vibe Coders !

Spent today's React session away from code — deep in Virtual DOM and Reconciliation instead.

Built a small counter project — not much, just enough to actually understand how useState works under the hood.

React needs to know about the change — that's the whole point of state.
