Answer 1

I can only recommend the docs
https://firebase.google.com/docs/database/web/read-and-write

Answer 2

Fixed successfully. The output [object Object] means that JSON is parsed when reaching output so I have added the parameter name to snap.val(), staying like this snap.val().name to give me the name that I have added, but if you want to get the json response, you need to JSON.stringify(snap.val())
Here it is the code
