How many code languages do I need to learn to build an app?

I already taken the html and css course, I am learning JavaScript. I want to know if with this 3 languages I can build an interactive web app with registered users and all of that. Do I need to learn server side development or data base languages?

If your app will involve persistent data (like users) that means a database. Plus, these are server-side functions.

JavaScript can be used on the server side, and you'll get an introduction to that if you're in the "Full Stack" track. Plus there are some additional courses available to extend server-side JavaScript.
