Review Summary
Thank you for your thorough test suite! However, there is a critical issue: the test for reducing an empty array without an initial value expects undefined, but according to the standard (see MDN documentation), it should throw a TypeError. Please update this test to expect a TypeError to ensure your implementation matches the standard behavior. Once this is fixed, your test suite will be fully compliant—great work otherwise! 😊

Issue: According to the standard Array.prototype.reduce behavior, calling reduce on an empty array without an initial value should throw a TypeError, not return undefined. If your implementation is meant to match the standard, this test should expect an error to be thrown instead of returning undefined. Please review the requirements and adjust the test accordingly.

Review Summary
Great job! 🎉 You have addressed the critical issue by updating the test to expect a TypeError when reducing an empty array without an initial value, which now matches the standard behavior. All other requirements are fully met, and your tests are comprehensive and well-structured. Keep up the excellent work!

Issue: The test expects undefined when reducing an empty array without an initial value, but according to the standard, this should throw a TypeError. Please update this test to expect a TypeError instead of undefined to comply with the standard behavior for Array.prototype.reduce.
