Js Higher Order Functions in Javascript
A Higher-Order Function (HOF) either takes a function as an argument OR returns a function (or both).
Examples of built-in HOFs: `.map()`, `.filter()`, `.reduce()`, `.sort()`, `.forEach()`, `addEventListener()`.
Currying: transforming a function with multiple arguments into a sequence of functions with one argument each.
Function composition: `const compose = (f,g) => x => f(g(x))` — apply g first, then f.
