The task explicitly provides an example arrayReverse(['Hell0']) === ['0lleH'] that is not currently tested; consider adding a dedicated test case using that exact input and output.


it(`should return an empty string
if original array consists of an empty string`, () => {
it(`should reverse multiple words preserving their original lengths`, () => {
expect(arrayReverse(['Mate', 'Academy'])).toEqual(['ymed', 'acAetaM']);
});

// write more tests here
it(`should handle a sentence with single letters and punctuation`, () => {
expect(arrayReverse(['I', 'am', 'a', 'student!'])).toEqual([
'!',
'tn',
'e',
'dutsamaI',
]);
});
