@@lineage13 I feel like they try to address the complaints they have about a certain language. The problem is, the complaints are usually just theirs, (or that of a few people) and in doing so, they introduce more issues. How many new languages have been dubbed the next "Java Killer"? I don't think Kotlin is the one either.

Great video Rahul. This was a good introduction to the language. I would like to add that it seemed that you're often explaining Kotlin from the perspective of a Java programmer. I can understand the need for it because a lot of Java libraries are used in backend development. However, Kotlin, given its multiplatform origins, stands independently. There are a lot of quality of life features like data classes, const variables, etc that you could tackle in a follow-up video.

It is by far the best introduction I have viewed. Thank you.
