Dove Combinator

Composes a binary function with a unary function on the right. Useful for applying a transformation to one argument before passing both to a binary function.

export const Dove = (x: Fn) => (y: Fn) => (z: Fn) => (w: Fn) => x(y)(z(w));
export const D = Dove;

const multiply = (x: number) => (y: number) => x * y;
const square = (x: number) => x * x;
const multiplyBySquare = Dove(multiply)(2)(square);
multiplyBySquare(3); // 18
