These questions were only shown to the developers who chose Scala as one of their three primary programming languages.
A year ago, a new major version of Scala – Scala 3 – saw the light of day. Since then, migration from Scala 2 has been going at a slow but steady pace. This year, Scala 3 is used by 28% of users compared to 10% a year ago. Scala 2.13 remains the most popular version (56%), while usage of older versions of Scala is on the decline.
On average, Scala developers are slightly older and have a few more years of experience than the average developer. They are involved in a more diverse set of activities including code reviewing, system design, testing, infrastructure development, and working with data.
