// Implement a caching function

const addNumbers = (a, b) => {
  for (let i = 0; i < 1000000000; i++) {
    // Do nothing
  }
  return a + b;
};

console.time("First time");
console.log(addNumbers(1, 2));
console.timeEnd("First time");

console.time("Second time");
console.log(addNumbers(2, 1));
console.timeEnd("Second time");
