Review Summary
Excellent work on the tests for the ifElse function! I am approving your solution as it correctly verifies the core conditional logic and meets the main requirements.
For future improvements, consider making your assertions more specific. The task description mentions that the callbacks should be called with no arguments. While your tests correctly check if the functions are called using toHaveBeenCalled(), you could use toHaveBeenCalledWith() to also verify they were called with no arguments. This would make your tests even more robust and fully aligned with all requirements.
This is a minor point, and your current implementation is solid. Keep up the great work!

These assertions are correct, but they could be more specific. The task description mentions that condition should be called with no arguments (and it's implied for first as well).
To fully test this, you could also:
- Make
conditionajest.fn()to check if it has been called. - Use
toHaveBeenCalledWith()to verify that bothconditionandfirstare called with no arguments.

Similar to the previous test, you can make these assertions more precise. The requirements explicitly state that condition and second should be called with no arguments.
Consider making condition a mock function and using toHaveBeenCalledWith() for both condition and second to ensure they are called correctly.
