Kotlin Blueprints

Destructing declaration

Kotlin is loaded with features. Some of the features are beyond our imagination. What if we tell you a function can return multiple values! Or you can catch the objects into multiple variables. Destructing declaration allows you to perform such things.

Let's say we need to return two things from a function. For example, a result object and a status of some sort. A compact way of doing this in Kotlin is to declare a data class (https://kotlinlang.org/docs/reference/data-classes.html) and return its instance.

In Kotlin, we can achieve this by writing the following code:
