Is Kotlin in demand

When talking about Kotlin and Java, both are good. But Kotlin, again, gives much more opportunities. Kotlin-JS gives you browser applications, Kotlin-Native allows to compile to native application (and interop with them).

Of course Kotlin and java have very much in common but I was surprised to find its similarities with Javascript . I was able to relate many concepts of Kotlin with that of Javascript and it made my learning much easier.
