In Javascript, we could use `Math.random()`. But if something goes wrong, we'd like to be able to repeat the test, using exactly the same data. In Javascript, we could use `Math.random()`. But if something goes wrong, we'd like to be able to repeat the test, using exactly the same data.
For that, so called "seeded pseudo-random generators" are used. They take a "seed", the first value, and then generate next ones using a formula. So that the same seed yields the same sequence, and hence the whole flow is easily reproducable. We only need to remember the seed to repeat it.
