Review Summary
Excellent work on the test suite for the arrayReverse function! I am approving your solution as you've successfully covered all the requirements from the description, including the specific examples and edge cases.
I have one small suggestion to make your tests a bit more efficient. In src/arrayReverse.test.js, you call the arrayReverse function twice with the same arguments. A common practice is to call it once, save the result to a variable, and then perform all your checks on that variable, which makes the test more efficient and readable.
For example:
const result = arrayReverse(['Mate', 'Academy']);
expect(result).toHaveLength(2);
expect(result).toEqual(['ymed', 'acAetaM']);This is just a minor tip for future reference. Great job, and keep up the fantastic work!

These are good assertions! However, you are calling the arrayReverse function twice here with the same arguments. It's a better practice to call the function only once, save its result to a variable, and then perform all your checks on that variable. This makes the test more efficient and often easier to read.
