How to install Scala in Linux?
Before, we start with the process of Installing Scala on our System. We must have first-hand knowledge of What the Scala Language is and what it actually does? Scala is a general-purpose, high-level, multi-paradigm programming language. It is a pure object-oriented programming language which also provides the support to the functional programming approach. There is no concept of primitive data as everything is an object in Scala. It is designed to express the general programming patterns in a refined, succinct, and type-safe way.
Scala programs can convert to bytecodes and can run on the JVM(Java Virtual Machine). Scala stands for Scalable language. It also provides the Javascript runtimes. Scala is highly influenced by Java and some other programming langauges like Lisp, Haskell, Pizza etc.
Scala is a very compatible language and thus can very easily be installed into the Linux Operating System. The most basic requirement is that we must have Java 1.8 or a greater version installed on our computer.
