Erlang excels in building concurrent and fault-tolerant systems, particularly in telecommunications, while Nim offers high performance and a more user-friendly syntax for general-purpose programming. Erlang's mature ecosystem suits distributed systems, whereas Nim's metaprogramming capabilities make it attractive for various application domains.
