Kids dad here. There's no doubt he had a ton of guidance - both parents are experienced programmers. Many things needed explaining to a 9yo, the same things that would have needed explaining to any new developer.

We went through MANY iterations (test-play/code-review + feedback + dev) before it was released to the public, which meant there was a lot of discussions and lots of opportunities for him to correct many small issues.

Some thoughts:

* DOCTYPE & meta utf-8 - he learned from Khan academy

* meta viewport - I showed him how to test for mobile and pushed to make mobile a priority

* const/let/backticks - he uses prettier in VSCode, which does this automatically

* code modularization - as a result of discussions around maintainability
