We have sent values to a function, but what about getting information back? All functions return to the location from which they are called and they return data using the “return” keyword. If you do not use the “return” keyword, the function will return “undefined”.
function add( num1, num2 ) {
let newNum = num1 + num2;
return newNum;
}
let addSum = add( 1, 2 ); // Variable to hold function call. Allows ease of use.
console.log( addSum ); // Displays 3Happy Coding!

The Credential Management API lets your site securely store and retrieve user credentials through the browser’s built‑in manager—no brittle autofill hacks required. In our demo, a successful login stores a PasswordCredential, and a single click later retrieves and auto-fills it for returning users. It’s a progressive enhancement: your form still works everywhere, but supported browsers deliver a faster, lower-friction sign-in. Pair it with proper autocomplete attributes today, and plan for WebAuthn/passkeys to level up tomorrow.
The Cookie Store API modernizes web cookies with async methods, typed objects, and change events—simplifying auth, prefs, and multi-tab sync.
