Hey, nice to see you back :).

I actually never heard of Kotlin, haha.
I use the TIOBE index of most popular programming languages to make my language selection, as I want to reach the most companies with my skills to earn an income.

The course I bought on Udemy uses IntelliJ, so I downloaded it, and I really like it :).

Thanks a lot for your advices and I wish you success with your projects.
