Get To Know: Why Scala Language is So Popular

Scala programming language

Stands for Scalable language, Scala is a general-purpose, high-level, multi-paradigm programming language that supports functional programming. Scala applications can be converted to bytecodes and run on the Java Virtual Machine (JVM) (Java Virtual Machine). This allows the Java and Scala stacks to work together seamlessly. 

Features of Scala Programming Language

Here are the salient features of the Scala programming language;

  • Ecosystem: Many tools and frameworks in concurrency support the Scala programming language for diverse implementations. For example, Apache Spark for large data, Apache Kafka for high-throughput messaging, and the Play framework for web app development.
  • Extensible language: Scala has a variety of language constructs that can be introduced as libraries to the language. Most crucially, Scala works with the Java Runtime Environment (JRE) (Java runtime environment).
  • Let You Create DSL: Scala offers many built-in capabilities, such as 'implicit' and 'overloaded operators,' that allow you to construct your domain-specific language (DSL) without having expert-level language knowledge.
  • Object-oriented: By default, every value in Scala is saved as an object. As a result, Scala supports first-class objects and anonymous functions.
  • Functional programming: Scala has an easy-to-use syntax for writing higher-order functions (i.e., you can pass a function as an argument to another function).
  • Concurrent and synchronized processing: Scala makes it possible to write immutable code for synchronised and concurrent processing.
  • Statically typed: The method of automatically testing and enforcing type constraints is inferred at compile time in Scala.

Usage 

Use 1# Use in Amalgamation with Java

Scala is a programming language that runs on the Java Virtual Machine (JVM). It is up to the individual using Scala to decide whether or not to use Java. One of the finest alternatives in Scala is Java's interoperability capability. This allows Scala programmers to use all Java libraries straight from Scala programmes. It is also advantageous for Java developers, since they can simply use their knowledge of Scala to their work. Scala code may also be called from Java, allowing users to write any part of a programme in Scala and the remainder in Java. As a result of this functionality, a user can develop code in both Java and Scala and collaborate with both languages.

Use 2# Use for Creating Dynamic Languages 

A statically typed language prevents programming errors and makes it easier for programmers to write and debug code. Errors in dynamic languages are only noticeable when you run a programme. Make the use of Scala combines the benefits of static and dynamic programming languages. It has a dynamic feel to it, yet it is a heavily statically typed language. Scala's type inference for variables and functions is far superior to Java's and C#'s type inference.

Use 3# Use for Writing Scalable Apps 

Scala provides a set of tools for quickly writing scalable concurrent programmes with more confidence in their correctness. Scala is an excellent foundation for parallel, distributed, and concurrent computing, which is usually regarded as a major hurdle in software development, but which Scala has overcome because of its unique set of features.
