flipAndCurry is a function that takes a function as argument, “flips” the order of arguments around, and then curries it.

flipandcurry_recipe.js

const flipAndCurry = (fn) =>
  (first) => (second) => fn(second, first);
  
// Example:
// https://gist.github.com/stefanfrede/596597d8b544de08491364eab20053c6
const mapWith = flipAndCurry(map);

// flipAndCurry throws the current context away, so it can’t be used to flip methods.
// A small alteration gets the job done:
const flipAndCurry = (fn) =>
  (first) =>
    function (second) {
      return fn.call(this, second, first);
    }
