Erlang Training Overview
This Introduction to Erlang training teaches attendees the fundamental concepts of Erlang, including its functional nature, concurrency, and error handling. This course helps attendees learn Erlang efficiently, stops them from making novice errors, ensures they are up to speed with the development workflow, and gets them thinking in the Erlang way.
