codewars.com is one of my personal favorites. over here you level up based on Kyu/Dan Ranks. This rank system has borrowed from a system in Japanese martial arts. one can level up by completing katas(problem sets) which are at or above their level. harder the kata, the faster you level up
boot.dev has a collection of 17 tracks on python, JavaScript and go. it includes an environment where the user can learn the required concepts and then immediately implement in a code playground integrated into the website. it also makes it really easy to track your progress and keeps you engaged as it has a ton of badges and achievements to collect as you code!
