Introduction to Scala Developer

Scala is the new world, well this is what makes the Scala Developers. Scala being a general-purpose programming language provides a platform for both functional as well as object-oriented programming approaches. Scala Developers are the ones who works properly on Scala Language working with the various methods and functions related to it. Scala Developer with the help of Scala as their main language work on the various object-related programming concepts. The Scala Developers play a vital role in Data Science and Data Analytics. Various Data Tools are written with Scala as the main language providing various libraries related to Data Processing and analysis.

Scala provides us with various API and libraries that make the developers comfortable for working with an object-oriented programming approach. Scala integrates the features of object-oriented programming making it easier for developers from Java or any object-oriented concept background.

Why Scala Developer?

Scala Developers are preferred in the market now day the reason being Scala is easy to learn, with developers having the access to write the queries in much simpler are easier form. It is a type-safe language from where we can work with both object-oriented as well as functional programming. The architecture of Scala makes a developer easy to understand and has more exposure to the industry.

The lines of code and the rules needed to write a JAVA code are comparatively much more complex and SCALA provides the features for writing it in a simpler way making it developers’ choice. The compilers used by the Scala developer are much smarter and environmentally friendly.

Let us check with an Example:

Let us create a List in JAVA.

Code:

import java.util.ArrayList; import java.util.List; public class HelloWorld{ public static void main(String []args){ list.add("1"); list.add("2"); list.add("3"); System.out.println(list); } }

Snapshot:

Let’s check that in scala:

Code:

object HelloWorld { def main(args: Array[String]) { val list = List("1", "2", "3") print(list) } }

Snapshot:

Scala developers came up with any method such as a map, flatmap making the looping and iterations easier for developers.

From this, we saw Why do we need Scala Developers and the benefit of having them in the industry.

Working Roles of Scala Developer

Let us see some Working roles of a Scala Developer:

Scala Developers deal with the object-oriented programming approach.

Scala Developers works with functional Data.

Scala can be used for various data analytics working model also like machine learning lib, R

Used for an end to end application development.

Various Big Data Environments are being set up using Scala as the main language.

End to End business development models is carried out in Scala Framework.

A huge exposure from the machine learning domain to web apps is available in Scala.

Many multi-core CPU arches is made using Scala language.

Many java related roles can also be clumped together with Scala making its exposure exposed.

Skills Required

A perfect Scala Developer must enrich the following Skills:

Must have programming experience.

Able to work on logic building and project architecture.

Having hands-on various programming rules like initialization of a variable, looping, memory allocation.

Having a computer background will definitely work.

Good knowledge of Scala IDE.

Able to extract the functionalities provided.

Analytical building approach.

Good knowledge of JAVA programming will always work.

Having the knowledge of Spark, BIG Data always works as Spark is written in Scala providing all the basic libraries for Big Data Processing.

Knowledge of Scala-based testing tools such as- Scala test, Specs2

Knowledge of Scala Build Tools (Sbt).

Knowledge of Scala Framework and libraries such as Scalaz, Cats.

Basic Scala functions such as- Pattern Matching, Case Class, Trait.

Conclusion

From the above article, we saw the importance of Scala Developer in the real world. From various examples and classifications, we tried to understand how the SCALA DEVELOPERS work and its usage in Scala Programming.

We also saw the skills required and the working role of Scala Developer, Also the working roles of Scala developer gave a clear picture about the industry exposure for the developers.
