FAQ
UUID v4 kya hota hai?
UUID v4 ek 128-bit random identifier hai — format: xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx. Ye random bits se banta hai, isliye collision ki probability practically zero hai.
Kya do UUIDs same aa sakte hain?
Theoretically possible, practically nahi — 5.3 undecillion (10^36) combinations hain. Aapko duplicate milne ke liye billions of UUIDs per second generate karne padenge, saalon tak.
UUID aur GUID me kya difference hai?
Kuch nahi — GUID (Globally Unique Identifier) Microsoft ka naam hai same cheez ke liye. Dono interchangeable hain.
Kya ye UUIDs secure random hote hain?
Haan — browser ka crypto.randomUUID() / crypto.getRandomValues() use hota hai jo cryptographically secure hai. Math.random() jaisa weak generator nahi.
