Questions
Which UUID version is this?
Version 4, which is random rather than time-based or name-based. The version and variant bits are set by the browser’s randomUUID implementation.
Can two of these collide?
A version 4 UUID has 122 random bits. A collision is not a practical concern for application identifiers generated this way.
