The exercise doesn't pass checking. What to do? 😶

In my environment the code works, but not here 🤨

My code is different from the teacher's one 🤔

I've read the lessons but nothing is clear 🙄

Found a bug? Have something to add? Pull requests are welcome!

Your exercise will be checked with these tests:

// @ts-check

import { expect, test, vi } from 'vitest'

test('hello world', async () => {
  const consoleLogSpy = vi.spyOn(console, 'log').mockImplementation(() => { });
  await import('./index.js')

  const firstArg = consoleLogSpy.mock.calls.join('\n');

  expect(firstArg).toBe('4')
})
