Ta’rif va qo‘llanilishi

$props obyekti komponentda e’lon qilingan props’ni ularning joriy qiymatlari bilan birga ifodalaydi.

Vue’dagi props — qiymatlarni bola komponentlarga atributlar sifatida uzatish usuli. Props haqidagi Vue darsligi sahifasiga qarang.

$props obyektidan, masalan, props’ni keyingi bola komponentga uzatish uchun (quyidagi 1-misolga qarang) yoki prop asosida hisoblanadigan (computed) xususiyat yaratish uchun (quyidagi 2-misol) foydalanish mumkin.

$props obyekti faqat o‘qish uchun mo‘ljallangan.
