Methods
randomUuid(withDashesopt, nullable) → {String}
Generate a RFC4122-compliant random UUID, as far as possible with JS. Generation is heavily dependent on the quality of randomization, which in some JS-engines is weak using Math.random. Therefore, we are using the specific crypto api if available and only fall back to random if necessary. Additionally, we track used UUIDs to never return the same id twice per reload.
