Even the best of things get the strongest of the competitor, not immediately but certainly. 

The same is the case with Groovy vs Scala. Both the programming languages are in demand for their unique characteristics and need. 

Mobile and web applications are in constant demand for various reasons. And this results in over 5 million mobile applications available. Hence, almost all the mobile app development company often looks for a reliable and strong solution. The solution that can offer the best in features for an ultimate & robust app development process. 

Here in this blog, we will be portraying the differences between Groovy vs Scala. But before that, let us quickly have a look at what both of these programming languages are all about. 

What Is Scala?

Created by Martin Odersky and came in 2004, Scala stands for “Scalable Language” is one of the functional and hybrid object-oriented programming languages. The language emphasizes on functional programming preferences. Scala market share can be traced through its interest over time-

When it comes to a quick debate between Groovy vs Scala, the later one has opted over the Java platform for general-purpose programming. Scala’s type system supports abstraction and parameterization. It basically evolved for integrating functional and object-oriented features. This approach results in making every value an object whereas every operator a method making a way for functions around variables. 

Furthermore, the language has a syntax for supporting anonymous functions and high order functions. It also supports paradigms like declarative and imperative along with describing algorithms at the level of abstraction. 

Moving on to the Groovy vs Scala core capabilities, Scala can be easily run on Java Virtual Machine and can be seamlessly integrated with the latter one. It is also possible to use libraries meant for Java, codes, interfaces, and subclass to a certain extent. 

But Scala is still concise and loops in it can be substituted by a single word. The process then makes it less verbose as compared to Standard Java. being statically typed embracing functional natures makes it type-safe too.

When it was about its basic structured information, there is a lot more to discover about it. Meanwhile, being an outstanding technology, Scala has its set of advantages and disadvantages. 

Let’s have a look at them too-

Advantages Of Scala Programming Language

  1. Object-oriented & functional programming language
  2. Compatibility and Interoperability with Java
  3. Scala is a concise programming language
  4. Class composition
  5. Processing in real-time
  6. Vast ecosystem
  7. Libraries for data science and data analysis
  8. Growing community

These points are just the crux, let us understand them in more detail. 

Compatibility & Interoperability With Java

Though Java is different from Scala but it does not make iOS and Android app developers to gauge the core. 

Scala being a strong programming language allows compatibility and interoperability with Java making developers- 

  • Takes the JVM advantages leverage
  • Using Java Libraries

Object-oriented & Functional Programming Language

Scala being an object-oriented programming language defines values as objects, types and object behavior as classes and traits. Also, the language as a functional language sees every function as a value.

Apart from defining things, Scala Programming Language consists of currying, immutability, type interface, pattern matching, lazy evaluation too. Other than that, it enables-

  • Robustness & conciseness
  • Renders design for parallelism & concurrency.

Scala Is A Concise Programming Language

Scala is known for making a swift balance between conciseness and readability. This makes it easier to understand. Its conciseness takes place due to-

  • Type interference
  • Pattern matching mechanism
  • Resuing utility and variables functions.

Class Composition

Next difference between Groovy vs Scala is that the later one developers for extending classes with sub-classing along with providing a flexible mixin-composition. 

Mixin composition is said to be one of the best ways for reusing code and is considered a replacement for multiple inheritances. 

Processing In Real-Time

Spark has given Scala a plus point as compared to other top-notch programming languages for processing streams that too in real-time. 

Vast Ecosystem

Next in Groovy vs Scala difference, Scala is capable of supporting a Java-based big data ecosystem. Java’s IDEs, frameworks, libraries along with tools smoothly work with Scala.

Libraries For Data Science & Data Analysis

Scala is capable of founding a base for big data projects. The language is filled with libraries and tools meant for machine learning, data analysis, and data visualization along with NLP. 

Growing Community

Scala has been noticed as a tool with the highest growth. The language also has an active community on Stack overflow along with Reddit and Github. 

Disadvantages Of Scala Programming Language

Scala was originally made to improvise the overall performance of Java. But due to its robustness, the language is difficult to learn and adopt. Apart from that, the language has a little weak IDE support and tools when comparing it with Java. 

With it, let us now summarize the meaning of what Groovy is all about.

What Is Groovy?

Another programming language when we talk about Groovy vs Scala is Groovy. It is both lightweight and user-friendly in the mobile/web app development world is Groovy. Groovy is one of the next object-oriented programming languages supported by the Apache Software Foundation. 

interest over time groovy

The language is compatible with the Java environment and uses scripting language or core purposes. Along with it, the language supports functional programming. Meanwhile, Groovy is somehow similar to Java’s Syntax. 

Furthermore, during the Groovy vs Scala  fight, the code enabled in Groovy can be integrated with the existing Java code. This will result in better usability. The language is often said to be a good fit for both dynamic and static programming. In many cases, Groovy is often considered as an alternative for Java programming. 

Let us now have a look at its advantages and disadvantages. 

Advantages Of Groovy Programming Language

  1. The language does have a flat learning curve which is concise, readable whereas the syntax is expressive. 
  2. Groovy got powerful features for builders, runtime, closures, and compile-time meta-programming. Apart from that, the language is popularly known for functional programming, static compilation and type interface. 
  3. Next in the line is Groovy’s smooth Java integration. The language enables seamless and transparent integration and interoperability with Java along with any third-party libraries.
  4. Groovy, the programming language also caters to domain-specific languages. It is flexible while carrying malleable syntax, advanced integration along with customizable mechanisms. All this is meant for integrating business-based applications. 
  5. Moving on, the language has a rich and vibrant ecosystem for developing websites and reactive applications. Also, the language is apt for concurrency, parallelism library, asynchronous, frameworks testing, code analysis, building tools, etc. 
  6. Last but certainly not least, the language is apt for scripting and testing. The language is great for concise writing and for test maintainability.

Disadvantages Of Groovy Programming Language

  • Groovy requires no source code formatter. This results in a reading code using different formatting. Meanwhile, CVS is difficult. 
  • The Groovy’s programming language plug-ins are buggy. 
  • For working with Groovy, the need to learn new concepts like closures are important to write and understand. 

With the core concept ready, let us now figure out the differnce betweeen scala vs groovy

Which Language Developers Should Use- Groovy Vs Scala

Both the languages carry their share of good points along with some disadvantages too. But at the same time, the language is compatible or better say apt for certain types of projects with special demands. 

9 Reasons To Choose Scala Programming Language This 2020

  1. Language With Multi-Paradigm
  2. Interoperability
  3. Built-In Language Patterns
  4. Expressiveness
  5. Easy Market
  6. Typed Statically
  7. Getting Uplifted Frameworks
  8. Growing Community
  9. Concise Syntax

This is just the crux, let us now get into the depth. 

Language With Multi-Paradigm

No doubt, Scala programming language is a little different as compared to Java because of two programming paradigms-

  • Object-oriented programming (OOP)
  • Functional programming (FP)

In order to advance programming skills, it is important to have a good command over a language from different programming paradigms. For example- functional, OOP, logical, imperative, etc. 

In the middle of all, Scala gives you the freedom for exploring both sides- OOP and functional. 

Moving on, the language is capable of defining types that are associated with data attributes & behavior attributes. 

Interoperability

The next point in the list is Scala framework interoperability. As Scala runs on Java Virtual Machine, it is easy to interoperate with Java code. 

This practice ensures that Scala developers can easily use Java libraries straight from Scala code. Apart from that, Scala code can be extracted from Java that will make it easy to write half part of a program in Scala and another half in Java. 

Interoperability with Java offers potential for coming into a mainstream enterprise programming language. 

Built-In Language Patterns

There are various practices and patterns that are built into the  language in order to overload the final keyword in Java against weird rules. 

Apart from that, the language carries case classes for creating immutable classes in Scala. It also offers closures- a feature that is integrated with Python and Ruby from the functional programming paradigm. 

Expressiveness

When comparing Java to Scala, the latter one scores a little higher than the former one. 

When comparing Groovy vs Scala, the former one is quite expressive with a plethora of beautiful and useful code. These impressive features attract more number of Java developers for learning Scala. 

Easy Market

When it comes to is Scala worth learning, there is no denying that learning Scala makes developers more marketable. This is the reasons, topmost businesses like Quora, LinkedIn, FourSquare, Twitter already made their way towards Scala. 

And in the coming years, financial institutions and organizations will fully adopt Scala for their low-latency solutions. 

Typed Statically

It is often noted by developers that Java is a programing language that lets them avoid issues and damages. To the amazement, Scala is developed dynamically and has been typed statically. 

Furthermore, Scala is smart while using type-interface to the full extent. While rendering all this, the programming language ensures type inference for functions and variables. 

Getting Uplifted Frameworks

When it comes to the next point in the context of Groovy vs Scala, the former ecosystem is growing. There are a plethora of libraries and Scala framework and many are about to be included. 

Several companies that have started the usage of Scala are together contributing to its growth as a mainstream language. Lift and Play are also the frameworks associated with Scala. Another of its framework like Akka has framed itself a toolkit for building highly concurrent, fault-tolerant, distributed and event-driven applications on the JVM. 

Growing Community

Community-associated with Scala is gradually growing resulting in Java developers joining the league. And this is not enough, IDEs too have started supporting Scala syntax along with a strong building tool support in SBT, Ant, and Maven.

Concise Syntax

Scala now has a new set of benchmark for being concise and readable, both at the same time. 

Meanwhile, Compiler for Scala known as Scala is more than what it looks like. 

7 Tech Companies Using Scala

The following companies are the right thing to show what is scala used for-

  1. Esentire- the company used Scala for building big data pipelines at the core of the product. 
  2. Curalate– the firm has used Scala for server-side projects along with building and deploying hundreds of microservices.
  3. Hiya– hiya used Scala for expressing large algorithmic meanings eliminating the need to write repetitive boilerplate code. 
  4. Axon- Scala’s rich type system made Axon precisely express the state of the entities for different situations. 
  5. Adcolony- the firm has inherited around 1,00,000 lines of Scala code with less test coverage. 
  6. Porch- they have used Scala for backend services that involve communication platform for managing emails, SMS, and Web-count chat, etc.
  7. Nortal– Nortal has used Scala for functional languages for making it fit in big data workflows smoothly.

Understanding these points, let us now figure out the reasons to choose Groovy for the next web/app development project. 

5 Reasons To Use Groovy Programming Language

  1. Easy to learn
  2. Smooth syntax
  3. Functionality
  4. Seamless integration
  5. Gradle

Let us now figure them out one by one in detail. 

Easy To Learn

The very first point in order to choose Groovy is that it is is easy. The codes that are written in Java can be compiled and work as expected when turning them up in the Groovy program. 

Apart from that though the learning curve for Groovy Programming Language is flat but not challenging for those who have fluent knowledge of Java. Also, there is no need to additionally learn everything for Groovy, discovering steps is easy with it. 

Smooth Syntax

When it comes to verbose, Groovy is less verbose as compared to Java. The elimination of unnecessary semicolons, syntactic sugar makes developers write faster without the need to worry about boilerplate code- something that makes it easy to answer what is groovy used for.

Functionality

For Java developers, the Groovy Programming Language paradigm might be confusing and quite new in terms of understanding the functionality. Meanwhile, learning functional programming in Groovy is still easy just like learning about other features. 

Seamless Integration

Both Java and Groovy Programming Language work flawlessly with each other. The classes made in Java falls perfectly with Groovy code back and forth without any additional glitch. 

Apart from that, there will no requirement for special language constructions or third party libraries. Also, the compiler made for Java would be seeing, using setters and getters generated by Groovy.

Gradle

When we say why is groovy more popular then scala, the answer lies in its tool power. Gradle, Scala’s build tool is gaining popularity. And due to this, tech giant Google has started using Grade for Android app development projects. 

Meanwhile, the graph below shows the difference between Scala and  Groovy performance 

groovy and scala interest with time

Apart from that, there is no necessary need to learn Gradle at a basic level whereas the in-depth understanding of it can help in decoding pro-level things.

Resting it, here is a detailed summarized version of both- Groovy vs Scala

comparison between scala and groovy

This is the end of the article but not the end of both the programming languages. 

Both the languages Groovy vs Scala are evolving and getting better with every passing day and in the coming year, there are high chances that these languages will be the core part of mainstream app development ecosystem.
