I am learning and studyng a lot of JS, and i love SoloLearn, but i dont know another language and I really like can train and practice JS. Can you add JS to code training? Do anybody know web pages to make exercices and practice javascrip??
You can try this site and I'm sure Burey , ChillPill , bobbie , and Danijel Ivanović may have several other resources... as well as there are other members of the community
When you open Code Coach and go to language selection menu, you can see JS and PHP there, so I hope it is coming in future. Otherwise there are other websites like for example https://www.freecodecamp.org/ , you can even earn some certification there. https://www.codewars.com/ was already mentioned. You can try some mobile apps like Enki, Stepik etc.
