Yara tana kakakin halika *sama* zuwa mahaifinta ta hanyar **aika da abubuwa**. Mahaifinta tana sauraro tare da `@event-name`. Wannan ya kammala juyayar bayanai na Vue: **props ƙasa, abubuwa sama**. ## Aikawa daga yara ```vue ``` ## Sauraron a cikin mahaifinta ```vue ``` Yara ba ta iya (kuma ba tai kamata) a canza bayanai na mahaifinta kai tsaye. A halin da ake gida ta *roƙi* mahaifinta ya aiki ta hanyar aika da abu tare da lodi; mahaifinta da ke mallar bayanai kuma ya yi canja. ## Me yasa a bayyana abubuwa tare da defineEmits ```js const emit = defineEmits(["delete"]); // documents the component's API // or with validation / TypeScript: const emit = defineEmits<{ delete: [id: number] }>(); ``` Bayyana abubuwan da aka aika, ya bayyana "fitarwa" na abu, yana bukatarwa jajirewa nau'in lodaje, kuma ya hana abu daga zaman sanye a matsayin mai sauraro na DOM na ainihi. ## Sauran mallakar sadarwa ```text props + emits → parent ↔ direct child (the default, most common) provide/inject → pass data deep down without prop-drilling Pinia store → shared state across unrelated/distant components v-model → two-way binding (props + emit sugar) ``` ## Me yasa ya ma'ana Aikawa abubuwa shine hanya na lamari da ake tsamani domin yara ta shafe jihar mahaifinta — kare juyayar bayanai na hanya ɗaya (wanda zai sauƙi manyan aiki su fahimci kuma su gyara ). Sanin `defineEmits` + `@listener`, kuma jiya a lokacin sake haɓaka zuwa `provide/inject` ko Pinia don sadarwan da ba mahaifinta-yara ba, ya maida jeri na sadarwa na abu na Vue.
