In this talk, Jeff will pull back the curtain on gen_statem and provide a useful reference for how and when to use it and why the apparent complexity might be worth it.

What are its strengths and weaknesses?

Is there anything gen_statem can do that GenServer can't?

In this talk, Jeff will explore these questions while providing some guidance and clarity on this mysterious behaviour available since the release of OTP 19.

OBJECTIVES
