Scala for Everyone
summary
Shows how Scala makes application development practical and accessible by using case classes and pattern matching to model a small environmental-impact app with far fewer lines than Java. Argues that static typing catches errors early and aids safe evolution, and demonstrates libraries that derive a single JSON schema for validation, serialization, and documentation; mentions tooling (WartRemover, compiler errors) and gives concrete recommendations such as using Option instead of null and Either for failures, plus tradeoffs for functional programming.
