How do you write with multiple coding languages in code playground?

Question

I saw people writing in Html, JavaScript and C++ . How do you do this?

Answer 1

At the top of the code editor, there is a box that has the current one. I think default is HTML/CSS/JS. Click on it and you can change it.

I'm on desktop version. Not sure if you're on app. :D Probably similar.
