Scala Programming

Scala is a high-level, general-purpose programming language that uniquely blends object-oriented and functional programming principles. Running on the Java Virtual Machine (JVM), it offers seamless interoperability with Java code and its extensive ecosystem of libraries, while its strong static type system helps prevent common bugs. Designed to be concise and expressive, Scala's name is a portmanteau of "scalable language," reflecting its power in building robust, concurrent, and distributed systems, making it a popular choice for big data processing with frameworks like Apache Spark.
