Kotlin Multi to Single Expression Functions
Dmitry Kandalov and I try the refactoring from Chapter 9 of Java to Kotlin, A Refactoring Guidebook (https://java-to-kotlin.dev/).
When a function can be defined as a single expression, Kotlin allows us to dispense with the braces and return statement. Apart from making everything a little more compact, I've found that aiming for single-expression functions can improve my code.
