![]() ![]() var testUUIDGenerator = function(generator, iterations, testCollisions, testValidity) /Ĭonsole.log((end.getTime() - start.getTime())) įirst Attempt return 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'. It works by accepting a generator as an argument. ![]() const uuid require ('uuid') After that, we will simply call the v4 function of this module, to generate a version 4 UUID. We will start by importing the uuid package we have just installed. This harness allows testing performance, validity, and collisions. In this section we will write a very simple code snippet to generate a v4 UUID. I created a test harness to test various generation methods. But, ULID considers both randomness and timestamp to generate IDs and they are encoded as 26 character strings (128 bits). Say you want to generate an RFC4122 version 4 compliant UUID in Javascript. When you generate an ID using UUID, it will generate a 36 character long string by only considering randomness or timestamp. ![]()
