# coroutines

[Steven McLaughlin]

Had a friend ask this:

how do kotlin coroutines work? i.e. is it just a state machine on top of Java's threadpool?

I don't really know anything about the internals. I thought maybe someone in here would have some insight

The core idea is that yes, it's a state machine.
This talk by Andrey Breslav is a bit older, but it goes into a lot of detail on how it works under the covers:

there is a newer version.
One from Andrey is a bit outdated

Anyone know what the guy in the first video at 1:33 is shouting?

[Steven McLaughlin]

Thanks! 🙂

@karelpeeters I think first one is "It blocks" and the 2nd one is "It's a style difference".

[karelpeeters]

Ah yes, that's it. What does he mean by that though 🤔

[diesieben07]

Well, he asks if there is something wrong with it, so I think it's a joke about the code style. Not quite sure either though.
