Add function for currying

function curry(func) {
  return function curried(...args) {
    if (args.length >= func.length) {
      return func.apply(this, args);
    } else {
      return function(...args2) {
        return curried.apply(this, args.concat(args2));
      }
    }
  };
}

Usage examples:

function sum(a, b, c) {
  return a + b + c;
}

let curriedSum = curry(sum);

alert(curriedSum(1, 2, 3)); // 6, still callable normally
alert(curriedSum(1)(2,3));  // 6, currying of 1st arg
alert(curriedSum(1)(2)(3)); // 6, full currying
