Is there any difference or major advantage with using auth.signOut() or signOut(auth) of them? This principle for sure also affects the same pattern for logging in, signing up, and so on. The firebase documentation (Web9) only uses the approach with functions signOut(auth). But most articles or tutorials using auth.signOut(). I guess it's a very basic question but I've seen everyone approaching it differently so I'm glad to solve this in the best way possible.

firebase.js

import { initializeApp } from "firebase/app";
import { getAuth } from "firebase/auth";

const firebaseConfig = {
  apiKey: "",
  authDomain: "",
  projectId: "",
  storageBucket: "",
  messagingSenderId: "",
  appId: "",
  measurementId: "",
};

const app = initializeApp(firebaseConfig);

export const auth = getAuth(app);
export default app;

Auth1.js

import { auth } from "./firebase.js";

// Option 1
function logout() {
  return auth.signOut();
}

Auth2.js

import { signOut } from "firebase/auth";
import { auth } from "./firebase.js";

// Option 2
function logout() {
  return signOut(auth);
}
