The B Combinator, or (variadic) compose.

variadic_compose_combinator_recipe.js

const compose = (a, ...rest) =>
  rest.length === 0
    ? a
    : (c) => a(compose(...rest)(c))

// Given:

const addOne = (number) => number + 1;

const doubleOf = (number) => number * 2;

// Instead of:

const doubleOfAddOne = (number) => doubleOf(addOne(number));

// We could write:

const doubleOfAddOne = compose(doubleOf, addOne);
