✅

The callback of the onAuthStateChanged method is bind to the wrong this scope. You can easily fix this by using an arrow function like below. When using an arrow function, it will automatically bind to the context it is defined in.

saveEmail() {
  firebase.auth().onAuthStateChanged((user) => {
    this.$root.email = user.email;
  })
}
