What kind of "Coding Language" is being used in these websites [closed]

I was wondering what kind of coding languages is being used in these websites and are there any tutorials to learn how to code such websites? are there maybe some website builders to ease the coding and UI?

here are the examples of the pages:

Is it Angular or React, PWA etc?

Thanks for your help & please stay safe and healthy! Constantin
