What does "Scala" mean in programming?
Scala is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
A statically typed language that runs on the JVM, combining object-oriented and functional programming. Scala is widely used for big data processing (Apache Spark is written in Scala) and high-throughput backend systems.
Example
"The data ingestion pipeline runs on Apache Spark, so the team writes ETL jobs in Scala."
