Review Summary
Thank you for your work on the test suite! At this stage, the PR cannot be approved because the current tests only cover a single, basic case and do not meet the core requirements for comprehensive coverage of the reduce function. Critical behaviors and edge cases—such as handling initial values, empty arrays, single-element arrays, sparse arrays, error handling, callback argument checks, and immutability—are missing from the tests. Please add tests for all these scenarios to ensure your implementation is robust and fully meets the task requirements. Once these are addressed, your PR will be ready for approval! Keep going—you're on the right track! 🚀

Review Summary
Thank you for your hard work on the test suite! 😊 While your tests cover many important scenarios for the reduce function, there are still a few critical cases missing that are required for full functionality and compliance with the task requirements. Specifically, you need to add tests for: (1) ensuring a TypeError is thrown when reducing an empty array without an initial value, (2) verifying the callback receives the correct arguments on each call, and (3) confirming that the original array is not mutated by the callback. Once you address these points, your test suite will be complete and ready for approval. Keep going—you're almost there! 🚀

Review Summary
Great job! 🎉 Your test suite for the custom reduce implementation is comprehensive, clear, and follows all best practices and guidelines. All critical scenarios from the MDN documentation are covered, including edge cases, error handling, and immutability. The structure and clarity of your tests make them easy to understand and maintain. All requirements and constraints have been fully met, and there are no outstanding issues or missing functionalities. Keep up the excellent work, and continue to pay attention to detail in future tasks!
