Crash Course on the Kotlin Compiler - Quick detour: K1 + K2 frontends, backends, and data transformations #kotlin #compiler #crashcoursekotlinc

https://link.medium.com/2PKnpiXI0zb

Well, I've been sitting on part 2 of the Kotlin Compiler article forever, mostly due to the nature of the review comments for discussing the differences between K1 and K2.

To be able to continue writing on resolution in a cleaner manner, I've decided to pull that discussion out into a quick detour - watch for tomorrow's release of "Crash Course on the Kotlin Compiler | K1 + K2 Frontends, Backends"!

Let's take a look at how `./gradlew generateTests` transforms the following code file to FIR and IR formats. The original code:

The FIR frontend, otherwise known as k2 frontend for the Kotlin compiler. Not pictured is the first form as an AST tree before PSI.

Just realized that my #compiler diagrams have been a depiction of K1 frontend the entire time 🤦 time to make updates
