State the advantages and disadvantages of Kotlin?

Advantages:

Kotlin is simple and easy to learn as its syntax is similar to that of Java.

It is the functional language that is based on JVM (Java Virtual Machine), which removes the boilerplate codes. Upon all this, Kotlin is considered as an expressive language that is easily readable and understandable and the performance is substantially good.
It can be used by any desktop, web server or mobile based applications.

In Kotlin, the function declaration can be done in many places in the application, which creates the trouble for the developer to understand which function is being called.
