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

Two way iframe communication

The main difference between the two pages is the method of sending messages. Recieving messages is the same in both.

Parent

Send messages to iframe using iframeEl.contentWindow.postMessage Recieve messages using window.addEventListener('message')

	const I = x => x;
	const K = x => y => x;
	const A = f => x => f(x);
	const T = x => f => f(x);
	const W = f => x => f(x)(x);
	const C = f => y => x => f(x)(y);
	const B = f => g => x => f(g(x));
	const S = f => g => x => f(x)(g(x));
	const P = f => g => x => y => f(g(x))(g(y));
	const Y = f => (g => g(g))(g => f(x => g(g)(x)));
