For quite a while, it's not going to be pretty, or something you can sell, but it will get you started. Keep building on what you learned. as you get better with just "making things that work," then work on making them better. Read, read, read, play, read. Don't worry if it looks bad, you need to conquer logic and data and achieving expected results before bothering with style.
...So now you think you can write stuff, next, look to see if it is secure. Could you hack your own stuff (probably easily early on), start looking for tips on how to tighten your work (start with anything affecting your stuff externally, data, calls, URLs, etc.) and make it safe for others to use, research common vulnerabilities, make sure you have them covered, etc. Also try to get some coding aesthetics in there, clean up code; name your functions, fields, variables sensibly, etc. Start constructing your project structure: configuration, code, library folders, sub-folders, etc.
Now look at end-user aesthetics (there's so many elements to developing, don't overwhelm yourself by doing them all at once). Act as if you are "the user", enter the data, play the game load, save - role-play as if it were one of your parents/grandparents, is it understandable?, easy?, fail-proof? (or is that "fool"proof?)
Enhance - now you can make some nice stuff. But from your perspective is it cool? Now you can work on getting in your style, new features, cut some edges...
Keep working it.
Then I recommend a few possible courses and I encourage them to pick a small project to work on to keep them motivated.
A kind HNer recommended two front end courses on Angular and React, but my friend recommends Vue.js. Do you have any idea what would be the best framework to learn for an inexperienced programmer that just wants to throw something together as soon as possible?
Take a look at the minimum features you absolutely need to support on the project. You may be able to get away with plain JavaScript rather than learning an entire framework.
