A modern programming language that makes developers happier.

kotlinlang

I'm writing Kotlin code, but I would like to see how it would look like in Java to see how much lines I'm saving.

That updates on the fly, but you need to manually hit decompile to see the Java code

That does not really tell you how much LoC you save because the Java code it translates to and the code you would write yourself a trip very different things. Especially when you use concepts from kotlin that do not exist in Java

Not really what I was looking, but that's great as well. I talked to Hadi Hariri on Twitter and he said, that what I saw during conference was just two separate files
