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) {
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))); |

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