Reviewing Kotlin

I have been teaching our rapidly growing team of Android developers Kotlin for about a year, and for the last few months, I’ve been reviewing tens of thousands of lines of code written by almost a dozen people at times. Here’s what we’ve found out together about learning, teaching, and reviewing Kotlin. I’ll tell you what worked for us and what didn’t, so that you may be more prepared for this path than we were. I’ll also point out some of the issues that most often arose in the code while our developers were getting familiar with the language.
