Review Summary
Great work on this task! The implementation of arrayReverse is correct and successfully meets all the functional requirements. Your tests cover the necessary cases, including the examples from the description and important edge cases.
I am approving your solution, but please pay close attention to the feedback on your tests in src/arrayReverse.test.js. Several test descriptions are inaccurate and do not reflect what the test is actually asserting. For example, the test described as handling an empty string actually tests two different non-empty arrays, and another description incorrectly states that spaces are kept in place.
Clear and accurate test descriptions are crucial as they act as documentation. For future projects, ensure each it block tests a single, specific scenario and that its description precisely matches the assertion. Keep up the great work!

The description for this test case is misleading. It states that it tests for an empty string, but it actually verifies two of the main examples from the task description. For better readability and maintenance, it's a good practice to test a single scenario per it block. Please split this into two separate tests with accurate descriptions.

The description 'should keep non-empty strings reversed' is unclear. A good test description should clearly state the scenario being tested. A better description here would be something like 'should correctly handle an array that includes an empty string'.

This test description is inaccurate. The function does not 'keep spaces in place'; spaces are reversed along with all other characters. An accurate description would be 'should correctly handle strings containing spaces'.
