Front end vs backend

hey can someone explain me wht is the difference btw front and backend

. which all languages need to study

Frontend is everything that is handled client-side, like a HTML/CSS/JS website. Backend is server-side, meaning you have code running on a server, rather than having it run client-size in a browser.

You can use HTML, CSS and JS to create the frontend. And with NodeJS you can also use JS for the backend.
