Projects that only receive occasional maintenance.Now, maybe you are at the crossroads of “migrate my existing projects” or “leave them as they are”, therefore, according to my experience, I leave a few points to keep in mind: But, if you have already experienced enough to decide that from now on you will use it instead of Java, Congratulations! You have really understood the potential that this language has. If you are starting to use Kotlin, you have most likely created new projects to experiment with this language.

Kotlin has become a programming language officially supported by Google for the development of Android applications.
