Scala is a general-purpose programming language created in 2001 to provide support for both object-oriented programming and functional programming. It was highly influenced by Java and designed to address some of its drawbacks, such as supporting operator overloading, optional parameters, named parameters, and raw strings, which make it easier to include characters such as html code that might otherwise have literal meaning within the language. Scala, which stands for scalable language, has a strong static type system, making it easier to avoid bugs in complex applications.
Scala source code can convert to bytecodes, so the ensuing executable code runs on the Java VIrtual Machine. It provides language interoperability with Java, meaning that libraries written in either language can be referenced in Scala or Java codebase. Scala is similar to other popular programming languages such as Java and C++, which makes it easy for developers to learn and begin using.
