What is Scala? 

First appeared in 2004, Scala is a statically typed general-purpose programming language that is mainly used to power backends in high-performance systems.

As stated earlier, it is a compiled language, supports both functional and object-oriented programming. Scala was particularly designed to be concise and address the shortcomings of a Java workflow.

To begin programming in Scala, you only need a Java Virtual Machine. The Scala code is compiled into bytecode and the JVM optimizes and executes it. Scala can also use all the Java classes and you can also create your own custom classes.

Being a high-level language, Scala is primarily used by data engineers and scientists for processing huge data. However, software engineers and developers have started using Scala for improving their productivity and build more efficient apps and tools. Next, take a look at some of the top companies using Scala in their tech stack to optimize their performance.
