Idk. The best thing to do is when u learn something new, be creative and make your own version to see how it could be used in other ways. If I didn't delete most of them, I'd have have hundreds of files where i just did my own side tasks to see how to do that specific thing.

Some good places to search/ask for help:

1. Repl.it. I (along with other helpers) will get pinged in discord if somone posts something in repl.it/ask and I am happy to help (although the bot might be a little slow)
2. https://stackoverflow.com (plenty of programmer memes about the op stackoverflow)
3. W3 schools (sometimes)
4. Tutorialspoint, an actual guide for learning coding languages might work as a tutor if it doesn't bore you to death

Most of all though, have fun, and don't over work yourself.
Keep up the good work ;)
