@sam-cooper.bsky.social - "Kotlin Brain Teasers"

Another tech review, and this one was right in my wheelhouse. I've done a lot of work with Kotlin and I was still learning new things throughout the book. The "Brain Teasers" series are always fun and this is my favorite.

Abusing a semicolon to save a line of code is not something I'd normally do in Kotlin! But in the book I really want the examples to stay short so they don't interrupt the flow of the text too much.

For succinctness, the star of the show here is Kotlin's also() function, though!

Okay, maybe I do want to brag 😄
