Atomic state model (Jotai, Recoil) yana gina halin jiya daga kusan ƙananan sassan da suke ba da izini wanda ake kira atoms, wanda ke haɗa daga ƙasa zuwa sama — maimakon wani girma babbar baje-jajiya (Redux) ko wani mahimmin haɗi. Abubuwan haɗa suke jido atoms na kewaye kuma kawai suke sake haɗa lokacin da waɗansu canje.

Kowane atom shine ɗayan yanayin kanta. Kuna yin gwargwadon yadda kuke buƙata, kowannensu na iya tunanin kansa.
// a derived atom computes from other atoms; recomputes when its dependencies change
const doubleAtom = atom((get) => get(countAtom) * 2);
const greetingAtom = atom((get) => `Hello, ${get(nameAtom)}`);
// writable derived atom
const upperNameAtom = atom(
(get) => get(nameAtom).toUpperCase(),
(get, set, newVal) => set(nameAtom, newVal.toLowerCase()),

Atoms suna tafiya cikin jadawali na dogaro — atoms da abin da aka samo suke sabuntawa kai tsaye lokacin da atoms da suke karantawa ba na canja, kamar takaitaccen alaƙa.

Redux (top-down): one big state tree; you carve slices/selectors OUT of it
Atomic (bottom-up): start with tiny atoms; compose them UP into derived state
Granularity: each atom is independently subscribable → naturally fine-grained
re-renders (a component using countAtom ignores nameAtom changes)
✓ Fine-grained re-renders by default (subscribe to exactly the atoms you use)
✓ No selector boilerplate; derived state is just another atom
✓ Solves Context's "re-render everything" problem
✓ Great for state that's naturally decomposed into many independent pieces
✗ Many atoms can be harder to organize/trace than one centralized store
✗ Less rigid structure than Redux (a pro or con depending on the team)
Atombashi model shine wata keɓantaccen hanya ta halin jiya wanda ke bulaɗe-bulaɗe hanyar Redux: a maimakon yanke babbar baje, kuna haɗa atoms ƙananan zuwa sama.
