Level 18: Testing Multiple Spaces

What if there are multiple spaces between words?

Plan: see how repeated whitespace converts by testing toSnakeCase('Hello World') and observing the underscore trio.

Show Me

it('should handle multiple spaces', () => {
  const result = toSnakeCase('Hello   World');
  expect(result).toBe('hello___world');
});

Try it: Add this test. Notice how multiple spaces become multiple underscores!
