JavaScript’s destructuring assignment syntax is a powerful tool for extracting values from arrays or properties from objects with ease. But what happens when the value you’re trying to destructure is undefined or non-existent? That’s where default values in destructuring come into play.
In this article, we’ll explore default values in destructuring and how they can be used to handle undefined values effectively, making your JavaScript code more robust and maintainable.
