Scala

What should developers avoid when building with Scala in early-stage projects?

The question is about Scala .

Answer:

Early Scala projects should avoid complex functional programming patterns such as tagless final, free monads, and effect systems like Cats Effect or ZIO until the team has solid Scala experience. These abstractions introduce significant cognitive overhead without matching benefits in small codebases. Avoid using Scala for projects where the team mainly knows Python or JavaScript, as the JVM ecosystem and Scala's type system create a steep learning curve that can slow early-stage development.
