Asynchronous programming might sound very compelling, but it is very difficult to master.
There are several pitfalls that you need to be aware of, such as the following:
- Race condition: If two or more threads of code modify the same data, the order in which they get executed can affect the final value. This race can lead to data being in an undetermined state.
- Starvation: Indefinite waiting by one thread due to other threads coming in.
- Deadlock: If a thread is waiting for a resource that another thread has locked, and vice versa at the same time, then both threads are stuck in a deadlock.
