My son (9 yrs old) used plain JavaScript to make a game, and wants your feedback 2 years ago
I completely agree that you can start using javascript directly without writing the so-called "children's programming language"
Perhaps he can try to use Github to get more feedback and try to colleborate with others :)
This is a 3D shooting game that I discussed with my nine-year-old son. The coding part was implemented by myself and AI.
Welcome to exchange experiences and ideas.
