The first chapter of
Introducing Erlang
encourages you to play around with the interacative erl system.
In this étude, keep using erl, but purposely make errors.
Try leaving out parentheses in arithmetic expressions. Try putting
numbers next to each other without an operator between them.
Try adding "adam" to 12. Make up variable names that you are sure
Erlang wouldn’t ever accept.
That way, you’ll get a feel for the sort of error messages Erlang produces and not be as baffled when you get errors that you aren’t expecting.
