Applied Functional Programming with Scala - Notes

1. Mastering Functions

A function is a mapping from one set, called a domain, to another set, called the codomain. A function associates every element in the domain with exactly one element in the codomain. In Scala, both domain and codomain are types.

val square : Int => Int = x => x * x

This is how I debug SystemStackError when there is no stack trace.

My first attempt was:

begin
  a_method_that_causes_infinite_recursion_in_a_not_obvious_way
rescue SystemStackError
  puts caller
end
