I have nothing against knowing how to code, but no 10 year old needs to be doing that, just going to make them even more used to a sedentary lifestyle and away from (real) social interaction.
You're better off targeting video games and social media, specifically the latter. Then again, kids don't even play video games, they watch someone else play video games.
Oh yeah, Twitch should be considered a health hazard for young impressionable kids. Wasting time and life away watching others play is something I just cannot comprehend.
