What potential security risks are associated with using JavaScript for password authentication in PHP applications?

Using JavaScript for password authentication in PHP applications can expose the password validation logic to potential attackers, as they can easily view the client-side code. This can make it easier for attackers to bypass the authentication process. To mitigate this risk, it is recommended to handle password authentication solely on the server-side using PHP. 

// Server-side password authentication in PHP
$password = $_POST['password'];

// Perform password validation logic here
if ($password === 'securepassword') {
    // Password is correct
    echo 'Authentication successful';
} else {
    // Password is incorrect
    echo 'Authentication failed';
}
