Level 11: Testing with Very Large Numbers

Now let’s test with very large numbers to see if our function handles them correctly:

Plan: stress-test add with a huge value and ensure it increments without overflow by asserting add(999999999, 1) equals 1000000000.

it('should add very large numbers', () => {
  const result = add(999999999, 1);
  expect(result).toBe(1000000000);
});

Try it: Add this test and run it. Does it pass?
