Scala vereint funktionale und objektorientierte Programmierung auf der JVM. Stark im Big-Data-Umfeld (Apache Spark) und bei anspruchsvollen Backends.

JavaScript läuft in jedem Browser und dank Node.js auch serverseitig. Unverzichtbar für Frontend, vielseitig im Backend, aber mit historischen Eigenheiten.
