What is Scala and How does Scala work?

Scala is a general-purpose programming language designed to express common programming patterns in a concise, elegant and type-safe way.

In this article, we will look at Scala in detail and will try to answer all your questions with regards to this programming language.

Let’s begin.


What is Scala?

Scala is a programming language that was created by Martin Odersky.

Scala’s main goal is to provide a general-purpose programming language which can be used in both industry and academia.

Scala has an all object-oriented code base, which provides the benefit of having full support for functional programming paradigms.

It also includes integrated features for making concurrent and distributed programming easier because scala’s JVM provides both multiprocessing and multithreading.

Scala runs on the Java Virtual Machine, and also compiles to Java bytecode so it can integrate with existing Java programs. Scala was designed to be concise and thus provide less code that will do more.

Scala programs compile to the same portable class files as Java programs do, and no wrapping or shims are needed for calls between Scala and Java code: they execute directly on the JVM without any overhead.

Scala syntax is quite different than that of Java or C#. It is more “compact” and less verbose than Java’s typical syntax.

What is Scala used for?

Scala is a computer programming language designed to express common programming patterns in a concise, elegant, and type-safe way.

This clean and powerful language enables users to write simple code that produces sophisticated software.

Why use Scala?

The best part about using Scala is that it’s compatible with Java libraries and tools. This means you can still use all the great code out there without having to learn new skills or languages!

Who uses Scala?

Scala is used primarily by companies to build their web apps. Though not a Scala-native, Twitter uses a Scala-based stack to power their APIs and analytics infra.

Another well known user is LinkedIn who have been using it to develop their mobile apps.

Facebook have been reported to use it for developing internal tools as well as crawling the web.

How to Install Scala?

There are two versions of Scala – Scala 2 and Scala 3.

Who invented Scala?

Martin Odersky invented Scala.

Can Scala be compiled?

Scala code may be compiled to Java bytecode and executed on a Java virtual machine (JVM). Scala and Java have language compatibility, allowing libraries built in either language to be easily referenced in Scala or Java programs.

Why is Scala faster than Python?

Scala code may be compiled to Java bytecode and executed on a Java virtual machine (JVM). Scala and Java have language compatibility, allowing libraries built in either language to be easily referenced in Scala or Java programs.

How to learn Scala Programming Language?

There are many ways to learn Scala. You can find many books on Scala if you want to read online for free. You can also check YouTube for videos.

You can also undergo Scala courses from Udemy, Coursera and various other popular online learning platforms.
