Ten Compelling Reasons to Go the Scala Development Way

Scala programming is hard but worth learning for developers looking to progress in their careers quickly. Scala is one of the few programming languages used as general-purpose and OOPS. Most of the fundamental concepts such as tuples, macros, and functions are based on OOPS (Object Oriented Programming Languages).

Developers already working with Java can compile Scala code inside a Scala compiler run by JVM (Java Virtual Machine).

Scala compiler ‘scalac’ compiles classNamees from code to bytecode run by JVM. The feature of language interoperability has been the most significant advantage of Sacal with Java. Scala was created to improve the programming complexities w.r.t. other languages. This gives an advantage to Scala over Java that is restrictive, requires more effort to program, and eventually frustrates developers.

Distinctions in coding and a paradigm shift from an OOP language often make learning Scala difficult. But the outcome after a few months of learning Scala is incredible for developers about easing the code complexities. Scala is a cleaner OOP language that has increased workplace productivity and proves to be easier to use.

The popularity of Scala is rapidly increasing. Hiring Scala developers for Scala development companies has become a trend on job portals.

What Scala offers is unique as compared to other OOP languages?

Scala development services are on the rise, with developers frustrated with coding in Java. Apart from just being another OOP language, Scala has unique features that differentiate itself from other languages: –

1. Scala Niche

Numerous technologies, tools, and frameworks support Scala and developers in their development journey. For example, developers use Apache Kafka to develop a high throughput messaging system and the Play framework for building web applications.

Some developer communities have also experimented with using Apache Spark for big data applications and services.

2. Scala Interoperability

Scala is considered an extensible language that extends its capabilities to other OOP languages. Multiple languages coding styles are supported in Scala, and developers enjoy adding multiple libraries from other languages in Scala.

Scala code is compiled by the JRE (Java Runtime Environment) in JVM. So, Scala is interoperable with Java via JVM.

Scala closely integrates with Java as the ‘scalac’ runs on the JVM, using its frameworks, libraries, and tools. This interoperability is a boon for MEAN stack development.

3. Scala DSL

Scala allows developers to create Scala applications in a DSL format. Scala has numerous built-in libraries such as ‘implicit’ and ‘overloaded operators’ that enable coders to create a DSL (Domain Specific Language). A DSL is usually created when developers do not have expert-level coding proficiency in specific programming languages.

4. Scala OOP

Scala is an inherent OOP language, and most of the fundamental concepts of Scala are based on OOP concepts. Every value used in Scala development is saved as an object by default. So OOP-based objects and functions are supported by Scala.

5. Scala functional programming

Scala has a lightweight independent syntax that developers use to create high-order functions. Coders are usually able to pass functions as arguments to other functions. The compiling and execution time is also fast, and Scala is faster than Ruby, Python, and node.js and hence is the most preferred choice for developers.

6. Scala synchronized programming

Scala allows developers to write immutable codes in an immutable manner. This facilitates the coders to program software applications in a synchronized way and helps in concurrent processing.

Web and desktop application development are supported cohesively in Scala, and Scala’s ability to compile JavaScript and JVM bytecode makes web and desktop application development more straightforward.

7. Scala static programming

Scala supports static programming. During compiling any application, developers verify and enforce different constraints on programs. Various constraints describe statically programming in Scala, and dynamic programming languages limit developers’ code security assurance.

The code is often filled with bugs and not robust. Static code is not to be tested at runtime scenarios because it is statically tested. Static coding does not always lead to potentially serious defects that never get realized until the code is in production.

8. Scala in JVM

Scala and Java share their runtime environment, i.e., the JRE. This has allowed programmers to move among both languages for execution in both environments. Scala is compiled in JVM and executed into existing Java projects very quickly.

Almost all of the Java SDK classNamees are also used by Scala development services. Hence, there arises no need to use a different compiler for Scala. Scala itself allows using existing Java libraries in Scala and enables the mixing of the Java Code. Also, by using the Scala libraries, a developer can use Java classNamees.

9. Scala Syntax

Scala developers use no semicolon in their scala program, and Scala does not enforce a semicolon after every statement. Instead, a newline character is used as the separator between lines. Enforcement of lesser syntactic code constraints makes Scala easier to learn and program. Unlike Java, C, and C++, learning Scala is effortless for Java developers w.r.t. its code reusability.

10. Scala for Big data

Scala is one of the most widely used programming languages by big data developers, and it is scalable on a JVM. A few of Scala’s best use-cases and applications on JVM are Apache Spark with Scala. This stack is currently being used on Alibaba and Netflix platforms. Cloud conglomerates such as Amazon, Microsoft, Google, and IBM use Scala for their backend operations.

Scala development companies motivate their in-house developers for these ten reasons to give them a heads-up in learning Scala. Conglomerates across various business sectors have moved most of their programs to Scala from other languages.

The primary reasons are concurrency, scalability, and the ability to code backend scripts for performing backend operations. Apple, Twitter, Walmart, Netflix, LinkedIn, Meetup.com, Google, Amazon, IBM, and Autodesk are hiring Scala developers.
