Title pretty much says it all. I had no trouble using these functionalities in Swift, but I'm struggling to use Auth in Javascript so I’m guessing I'm missing something simple. Everything after my "if (auth.currentUser)" isn't running in login_credentials(), and if I remove that check none of the following alerts or logs appear either in my signInWithEmailAndPassword() call. Thanks in advance.

Here is my index.html:

```html

h1 {text-align: center;}
h2 {text-align: center;}
h3 {text-align: center;}
form {text-align: center;}

and here is the section of my index.js relating to sign in (config values hidden for privacy):

```js
require("firebase/app");

require("firebase/auth");
require("firebase/firestore");
const firebaseConfig = {
apiKey: "",
authDomain: "",
databaseURL: "",
projectId: "",
storageBucket: "",
messagingSenderId: "",
appId: "",
measurementId: ""
};

firebase.initializeApp(firebaseConfig);
const auth = firebase.auth();

function login_credentials() {
var email = document.getElementById("email").value;
var password = document.getElementById("password").value;
if (auth.currentUser) {
// [START signout]

auth.signOut();
// [END signout]
}
alert("test") //doesn't show up unless above the if statement

auth.signInWithEmailAndPassword(email, password)
.then(function(firebaseUser) {
alert(firebaseUser.credential);
})
.catch(function(error) {
var errorCode = error.code;
var errorMessage = error.message;
window.alert("alert: " + errorCode + ": " + errorMessage);
console.log("error: " + errorCode + ": " + errorMessage);
});

}
```
