Kotlin offers many features of modern languages. It has null safety, a functional style of coding, non-verbose code, and is clean and easy when it comes to using Java's stream operations, including filter, map, reduce, and more. All of these can help to improve your development life cycle and productivity.
Kotlin was developed with the intention of adding features that are not found in existing JVM languages. It is a modern JVM language that has full interoperability with Java, ensuring that existing applications or services don't face any problems with coexisting with Kotlin. If we are familiar with functional paradigms, it will be easier to make use of the power of the language.
