My own implementation of curry 🍛

curry.js

// Ultimate version
const curry = (f, ...args) =>
  f.length <= args.length
    ? f(...args)
    : x => curry(f, ...args, x)

Thanks @kutyel! I'd remove all the additional parameters. For example, this situation would be possible:

const sum = (a, b) => a + b;
const curriedSum = curry(sum);
const wrongCurriedSum1 = curry(sum, 2); // a function with one parameter
console.log(wrongCurriedSum1(3)); // 5
const wrongCurriedSum2 = curry(sum, 2, 3); // not a function, but 5
const wrongCurriedSum3 = curry(sum, 2, 3, 4); // not a function, but 5

Thanks again!
