Scala: The Simple Parts
summary
Scala centers on a compact claim: seven composable primitives — expressions, nesting scopes, pattern matching & case classes, recursion, function values, immutable collections and controlled vars — are sufficient to scale from scripts to large systems. Evidence: an ecosystem of DSLS and a new fast compiler dotc that uses caching, copy‑on‑write and careful mutable caches; community size cited around 100,000 developers and 200,000 Coursera subscribers, and recent releases show dramatically improved incremental build times.
