Java to Kotlin: A Refactoring Guidebook

Sample Chapter 7 - Actions to Calculations

25 August 2022

We have found Eric Normand’s division of code into Data, Calculation and Actions very useful. He introduces the concept in his excellent podcast and book Grokking Simplicity.

Unfortunately he doesn’t (yet) seem to have written about the subject on the web. To fill this gap, we’ve published the introduction to Chapter 7 - Actions to Calculations, which is our interpretation of at least part of the concept.
