what language is sololearn coded in?
I know it's a weird question but definitely the guys who make sololearn know a lot of languages so... probably the ios is on swift and the android is on java... but what about the web page for example? Is that one in html, css, js format? And obviously an iphone cant translate high level stuff like python or ruby into machine language. So that's probably on a server. And what code is on the server then? Php? Python? Anybody know the answer im very curious about it
