الأسئلة الشائعة
What's the difference between v4 and v7?
v4 is 122 bits of randomness. v7 puts a 48-bit millisecond timestamp in the first bytes, so IDs are sortable by creation time - much better for database primary keys.
How random are these?
They use window.crypto.getRandomValues, the same source used for TLS keys. Not Math.random.
Are the UUIDs stored?
No. They're generated and displayed locally - nothing is sent to any server.
