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

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