vuid
very unique identifiers
This module exports a tiny (144B) function that generates UUIDv4 compliant identifiers in the browser. It takes advantages of and relies on the browsers built in crypto API namely the getRandomValues function. This offers a better level of randomness than Math.random but means will not work in a node environment.
For all practical purposes the generated identifiers can be considered universally unique. The chance of two ever colliding is 1 in 5,316,911,983,139,663,491,615,228,241,121,378,304. Which is a pretty cool guarantee.
