The interface we are using in solo learn is made of which language?

Question

Actually I wanna ask which programming language is used to make the learning environment of solo learn?

Answer 1

In the web version it most likely uses html, css, and javascript. While In the app version, it most likely uses the Material API, XML, and Java. Lastly, for the servers the requests and data maybe are handled by PHP and MySQL, like saving a code or updating someone's course progress.
