Review Summary
Excellent work on this task! Your solution is approved. The createTree function is correctly implemented using recursion, and the project structure is clean and meets all the requirements.
As a small suggestion for improvement, consider what happens if an empty object is passed to the function. Your current implementation adds an empty <ul> to the DOM. You could make it more robust by adding a check at the start of the function to return early if the data object is empty. This is just a minor point for future consideration.
Overall, this is a solid implementation. Well done!

This implementation creates and appends a <ul> element immediately. If the data object passed to the function is empty, this results in an empty <ul> being added to the DOM. It would be better to only create the list if there are items to put inside it. You could add a check at the start of the function to see if data has any keys, and return early if it's empty.
