Bluebird Combinator

Standard function composition. Composes two unary functions, applying the second function first.

export const Bluebird = (x: Fn) => (y: Fn) => (z: Fn) => x(y(z));
export const B = Bluebird;
export const Compose = B;

const addOne = (x: number) => x + 1;
const double = (x: number) => x * 2;
const addOneThenDouble = Bluebird(double)(addOne);
addOneThenDouble(5); // 12
