I think both explanations are part of the bigger picture of what actually the event loop does. async tasks are assigned to the thread pool and when finished their call back functions are put in the event queue. when nodejs's execution stack is empty, the event pool takes the first cb from the event queue and puts it back in the stack for execution

Would you have an example of a good diagram? Share with us, please!
You read about event loop here.
Thanks a lot for sharing, for sure I'll read about it!

Just edited my comment with the explanation/video — I hope it helps.
