Javascript Algorithm & Data Structures Projects

I have done Cash Register Projects and would like to get more projects to hone my JS algo skills. Please let me know if there is any similar projects that require skills up to this level of curriculum

the Cash Register project is one of the final projects to get the certificate. If you want to exercise with solving algorithms there is the Interview Prep section (almost everything in there is algorithms to solve, just ignore for now the Take Home Projects section), which is mostly algorithms, or other websites like for example (in which you get more difficulgt algorithms as you do them)

Thanks for your reply. Codewars seems interesting
