Enlist major features of Kotlin?

Kotlin was developed to make it feature-rich in mind, so there are many features that make Kotlin a unique programming language.

Below are some major Features of Kotlin Programming Language:

1.Extension functions: In Kotlin, you can add some extra functionality to the existing component to make it much more versatile.
2.Higher-Order Function: You can pass a function as an argument to a method or return a function as a result of the method in Kotlin.
3.Smart Cast: Smart Cast checks for some type, and then it will allow performing all the operations allowed for that particular type.
4.Destruction Declaration: With this, it is possible to return more than one value from a function.
5.Default and Named arguments: You can assign a default value to the parameter whom you want to make optional, and while calling that method, there is no bound on giving values to the default parameters. You can easily change the sequence of the parameter at the time of calling with Named arguments. It is done by writing the name of the argument and then assigning the value to it.
