When to choose C

  • Choose C for Operating system kernels (Linux, Windows NT), Device drivers and firmware, Embedded systems.
  • C has the clearest quantitative lead in memory efficiency.
  • Watch out for manual memory management — leaks and corruption are common.
♾️

When to choose Scala

  • Choose Scala for Apache Spark / Big Data pipelines, Distributed systems (Akka), Financial systems with complex domain logic.
  • Scala pulls ahead most clearly in type safety.
  • Watch out for notoriously steep learning curve.
