JavaScript Double Question Mark (??): What is it?

As one of the most powerful programming languages in the world, JavaScript has an array of features that allow developers to create visually appealing and dynamic web applications with ease. One such feature is the double question mark (??), also known as the nullish coalescing operator. This logical operator works by returning the right-hand side operand only when the expression on its left is null or undefined, making it an excellent tool for developers looking to write concise, error-free code.

If you're looking to master the art of JavaScript programming, familiarizing yourself with the nuances of the nullish coalescing operator is a must. By harnessing the power of this feature, you can streamline your code and eliminate common errors, helping you build robust, reliable applications that stand the test of time.

So whether you're an experienced developer or just starting with JavaScript, dive into the world of the double question mark, and take your programming skills to the next level!
