Hey guys! I already finish the JS course, and I would like to keep practicing JS, there is an IDE to do that? Or just my notepad? I really would like to work in a enviroment like the one here in CodeCademy (so if you know one, let me know).
I already checked sublime, but i don’t even know how to run my own code!

If you want to test your code online try jsbin

Guys, thank you for your answers. I think I haven’t explained well, I need to keep practicing just the logic, doen’t need it link it with html and css websites yet. Just need the logic and use the only programme language that I know (JS) to solve some math problems.
Hope you can help me. Thank you!
Yes you will run it in the same was as you would with a website. You don’t need to include CSS ect…
