Answer 1

Here's what I did and it worked.

        function registerUsername(email,password,displayName){
            firebase.auth().createUserWithEmailAndPassword(email, password).then(function(value) {
                console.log(value);
                }).catch(function(error) {
                    console.log(error);
                });
        }
