How to change [object object] from firebase to a string? [duplicate]

Question

I get an object from my code

       const username = await firebase
        .database()
        .ref("users/" + authUser + "/name")
        .once("value")
        .then(function(snapshot) {
          return snapshot;
        });

Its value is "testname". Its logging everything correct to console. But if I try to reuse my username for example in

      const url = `https://url.com/users/${username}/${authUser}/posts.json?auth=${token}`;

I get in my console.log

https://url.com/users/[object Object]/...

I am pretty new to firebase and JS but I think I have to transform my object to a string? How to achive this?

Got it now via var myJSON = JSON.stringify(username); But it return "testname". Do you know how to get rid of the ""? — Brydawg

I am writing via REST Api to my firebase with the username. The structure is now /users/"testname"/posts but should be "users/testname/posts — Brydawg

yourString.substring(1, yourString.length-1) or go with yourString.slice(1, -1); — joy08
