What is Scala and why it is used?
Scala, is a general purpose, hybrid functional programming language. Integrating the features of other technical and object-oriented languages, Scala is designed to run on JVM. Scala provides lightweight syntax that helps developers define anonymous functions. Scala allows developers to write general programming patterns efficiently by reducing the number of lines. This language also empowers the developers to write immutable codes, thus making it easy to apply parallelism and concurrency.
The unique feature that makes Scala standout from the rest is its ability to scale and expand. It has almost eliminated the common problems associated with other popular languages.
Why it is used?
Scala can be used in many ways, including in android apps, desktop apps, data processing, front-end and back-ends of web applications, Hadoop programs, big data, and data analysis, data streaming, etc.
