Lalu ada masukan, coba pikirkan ketika user akan menambahkan kondisi tambahan selain foo 3 dan 5 bar diatas, misal menambah 7 sebagai fizz, atau mengubah 5 menjadi buzz, apakah program kamu saat ini sudah support dengan penambahan kondisi tersebut

Sudah saya tambahkan mas, bisa dicek misal perlu saran lagi 😁
