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

	<%
	director_uuid = 'CHANGEME'
	static_ip = 'CHANGEME'
	root_domain = "#{static_ip}.xip.io"
	deployment_name = 'cf'
	cf_release = '170'
	protocol = 'http'
	common_password = 'c1oudc0wc1oudc0w'
	%>
