Svelte Props Events Export Let Createeventdispatcher Bind

Definisi

Komponen child menerima data lewat props (export let) dan mengembalikan sinyal ke parent lewat events (createEventDispatcher) atau langsung bind ke prop (two-way).

Kapan dipakai

• Props: kirim data satu arah parent → child.
• Event dispatcher: child perlu memberi tahu parent (klik, submit, selesai).
• bind:prop: child boleh mengubah nilai milik parent (gunakan hati-hati).
