A modern programming language that makes developers happier.

kotlinlang

Re learning programming with Kotlin, I was teaching my son the basics with Kotlin, it was really smooth. You can start with simple procedural stuff with `println`, no complex graphics, no objects, no functions. First teach decomposition with functions, then introduce a little bit of data classes without any methods, etc. The most complex thing to teach was actually not something specific to Kotlin, it was “memory model”, i.e. how data is represented inside a computer memory, the concept of a “reference”, the concept of a type of a memory data (even if as simple as String or data class), etc. YMMV, but I believe Kotlin is really good for teaching.

May I ask why you didn't start earlier? Do you think it was too early? 
I am really interested about because I'd like to teach mine as well
