+### Compose
+
+Use `Array.reduce()` with the spread operator (`...`) to perform right-to-;eft function composition.
+The last (rightmost) function can accept one or more arguments; the remaining functions must be unary.
+
+```js
+const compose = (...fns) => fns.reduce((f, g) => (...args) => f(g(...args)));
+/*
+const add5 = x => x + 5
+const multiply = (x, y) => x * y
+const multiplyAndAdd5 = compose(add5, multiply)
+multiplyAndAdd5(5, 2) -> 15
