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!

Intercommunication between different contexts (like tabs, iframes or workers) of the same origin has often been a challenge. With the Broadcast Channel API, developers now have a powerful tool to easily communicate between browsing contexts. In this blog post, we’ll dive deep into the capabilities of the Broadcast Channel API, exploring its features, use cases, and how it can be effectively implemented in your projects.
Wireless communication has become an integral part of our daily lives, and Bluetooth technology is at the forefront of this revolution, enabling devices to exchange data over short distances and creating a world more interconnected than ever before. At the heart of this technology lies the Bluetooth Application Programming Interface (API), a powerful tool for developers looking to harness the capabilities of Bluetooth in their applications. In this blog post, we’ll explore what the Bluetooth API is, how it works, and the possibilities it opens up for innovation in wireless communication.
