languages.lessons.show.profession_description

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:

import { expect, test } from 'vitest';
import f from './index.js';

test('test', () => {
  expect(f(2, 2)).toEqual(2);
  expect(f(1, 3)).toEqual(6);
  expect(f(1, 5)).toEqual(120);
  expect(f(2, 5)).toEqual(120);
  expect(f(0, 5)).toEqual(0);
  expect(f(-4, -2)).toEqual(-24);
  expect(f(-4, -3)).toEqual(12);
});
