Erlang Skills Test

1. What is Erlang?

It is a runtime environment and general-purpose programming language. It simplifies concurrent programming for programmers. Instead of using shared variables to exchange data, the processes use message passing, which does away with the requirement for locks. It is an effective framework for fault tolerance and error containment.  

2. Why use iMocha's skills test?
