You're passing `this` in an arrow function, which is a mistake.

…  return cache.get(key);
    } else {
      console.log("Calculating result");
      const result = fn.apply(this, args);
      cache.set(key, result);
      return result;
    }
  };
};

You're passing `this` in an arrow function, which is a mistake. It will pass global context instead of caller context.
