Debugging JavaScript Uncaught SyntaxError: Unexpected token ‘;’ [closed]

I have a problem with the last line. Does someone know how to fix this code?
The “console” says: Uncaught SyntaxError: Unexpected token ‘;’.
Thanks

var userDatabase = [
    {
        username: "Admin",
        password: "4444",
    }
];

var newsfeed = [
    {
        username: "Max",
        timeline: "Good Morning!",
    },
    {
        username: "Alex",
        timeline: "Have a cool day!",
    }
];

var signUpName = prompt("Enter Username");
var signUpPassword = prompt("Enter Password");

function login(a, b) {
    if (a === userDatabase[0].username && b === userDatabase[0].password) {
        console.log(newsfeed);
        } else {
            alert("Wrong Details");
        }
}
    
function login(signUpName, signUpPassword);
