A Guide to Functional Programming Lingo for JavaScripters

Functional programming gets a bad wrap about being too hard for mere mortals to comprehend. This is nonsense. The concepts are actually quite simple to grasp.

The jargon is the hardest part. A lot of that vocabulary comes from a specialized field of mathematical study called category theory (with a liberal sprinkling of type theory and abstract algebra). This sounds a lot scarier than it is. You can do this!

All examples using ES6 syntax. wrap (foo) => bar means:

function wrap (foo) {

Should be work with 0.18

Destructuring(or pattern matching) is a way used to extract data from a data structure(tuple, list, record) that mirros the construction. Compare to other languages, Elm support much less destructuring but let's see what it got !

Tuple

myTuple = ("A", "B", "C")
myNestedTuple = ("A", "B", "C", ("X", "Y", "Z"))

	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)));
