A modern programming language that makes developers happier.

kotlinlang

currently use kotlin for backend and  not an app engineer so i dont understand most article on coroutines which target android folks.

Coroutines are not really different between front end and backend. The most notable differences may be how you use them, and the presence of a main dispatcher in front end. In front end you might typically write in a more reactive style.

For backend just look up anything backend related that is implemented using coroutines... ktor, database stuff..
