For educational reasons I've decided to create my own CA. Here is what I learned.
Lets get some context first.

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.
Unidirectional is a term coined by React engineers to describe the data flow of an application. Unidirectional apps employ functional reactive programming techniques such as immutability, purity, and most importantly unidirectional (as opposed to bidirectional) data flow.
A unidirectional app is defined by no mutable references no two-way references between concerns.

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.
