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

	* Extend this trait to create your application config

	* Pros of this approach:
	* 1) Library free approach - only 15 lines of dependency free "library" (four one-line defs for you to override)
	* 2) Failures happen when the Config object is loaded instead of when a config value is accessed
	* 3) Strongly typed
