 One of them is testing. We may need random data: text, numbers etc, to test things out well.
 
-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 reproducible. We only need to remember the seed to repeat it.

 - Inside generators (only) there exists a `yield` operator.
 - The outer code and the generator may exchange results via `next/yield` calls.
 
-In modern Javascript, generators are rarely used. But sometimes they come in handy, because the ability of a function to exchange data with the calling code during the execution is quite unique.

 Also, in the next chapter we'll learn async generators, which are used to read streams of asynchronously generated data in `for` loop.
