Code Examples
JavaScript
const ids = Array.from({ length: 5 }, () => crypto.randomUUID());Python
import uuid
ids = [str(uuid.uuid4()) for _ in range(5)]Frequently Asked Questions
Are the 5 values guaranteed different?
Yes in practice — the chance two v4 UUIDs in a batch of five collide is about 1 in 10³⁶.
Can I mix versions in one batch?
A batch uses one version. Generate 5, then switch the version and generate 5 more.
