Hire Scala Developers

Over the years, many programming languages have become popular and fit into the needs of their era. There has always been a craze for object-oriented programming languages like C++. However, today’s applications are modeled based on functional programming to meet the concurrency, heterogeneity, round-the-clock services, and shrinking development schedule demands. A perfect mix of object-oriented and functional programming paradigms has become the need of the hour in modern computing.

Scala is the right choice of a general-purpose programming language that supports both object-oriented and functional programming approaches. It is scalable and can cater to all applications ranging from scripts to large-scale applications. Scala is already in use by many organizations around the world. It is a powerful language with the benefits of a modern-world object model, functional programming, and an advanced type system powered by the investment in the Java Virtual Machine.

Scala – A Scalable Solution for Large-Scale Enterprise Applications

Martin Odersky, who developed Scala in 2001, has incorporated optimal qualities in the language to create reliable, high-performance, highly concurrent enterprise applications making it an indispensable programming language. He has been part of the development of Java for years and understands the requirements of programming highly reliable, large-scale, modern applications and middleware.

Why Developers Choose Scala?

Scala is the language that can cater to the needs of modern software developers. It has a concise, elegant, and expressive syntax format and an entire breadth of tools on offer. It is a multi-paradigm, scalable, sophisticated, and practical language.

Scala’s design is inspired by the intelligent features of different programming languages. There are only a few completely new features in Scala, and most of the other features are applied in other languages. Scala adopts a large part of the syntax form of Java and C#. Compared with Java, Scala has the expressions, statements, syntax of classes, packages, imports, and blocks as in Java and has also adopted Java’s basic types, class libraries, and the execution model. The object model that Scala uses is similar to Ruby. The actor-based concurrency library that Scala features is inspired by Erlang. Scala also has features that inspire future programming languages, such as the abstract types, the traits for flexible component assembly, and the extractors that facilitate representation-independent pattern matching.

Some of the salient features of the language are listed below.

1. Mixed Paradigm Support

Scala supports both object-oriented and functional programming paradigms. It leverages Java’s object-oriented model with additional traits to facilitate a mixed paradigm approach. It also supports the functional programming approach to resolve concurrency issues, implementing functions without side effects and function collections for powerful, correct, and concise code.

2. JavaScript and JVM language

Scala leverages the robust performance of the JVM and the powerful tools and libraries of Java and supports the JavaScript language too.

3. Sophisticated and statically typed system

Scala builds on the type system of Java with flexible enhancements to facilitate code correctness. The type inference feature in Scala helps in concise coding compared to other dynamically typed languages. Scala can create robust applications with its static typing feature. This feature eliminates the problems of Java’s type system by substituting it with type inference.

4. Flexible syntax format

Scala helps developers build domain-specific languages and APIs that look native to users. The flexible and concise syntax format allows the developers to write manageable code compared with the elaborate syntax method followed in Java.

5. Scalable language

Scala is a highly scalable language that can support small scripts to large-scale enterprise applications. The language derives its name from the words “Scalable language.”

Advantages of Functional Programming

Scala supports a multi-paradigm approach by providing a hybrid environment to use object-oriented features and the functional programming concept. Functional programming concentrates on what the program needs to do to resolve the problem rather than how it should be done in contrast to imperative programming. The programmer tells the system what to do.

Scala utilizes the advantages of functional programming listed below.

• Less code – A functional programming approach involves writing less code compared to imperative programming. As the developer writes less code, it is easy for them to understand and maintain the code. This helps increase the developer's productivity as they spend less time going through the code.
• Referential transparency – As functions are entirely described for the data that goes in and comes out, it makes it easy and safe to reuse these functions for different scenarios. The functions are quite easy to develop, test, and maintain too.
• Recursion – A functional programming approach uses recursion to process structures as the looping constructs in an imperative language.
• Modular functionality – As functional programming is modular in terms of functionality and not by components, it is the perfect choice for component reusability.
• Partial evaluation – As the functions are created without side effects, it makes it easy to bind one or more parameters at compile-time and reuse these functions effectively with bound values.
• Good for prototyping solutions – Solutions can be created easily with a functional programming approach that allows for exploring new ideas in a rapid application development environment.

However, a functional programming approach has a few disadvantages, as listed below.

• Interactive applications are harder to develop with a purely functional programming approach as they are created based on request responses initiated by user action.
• The functional programming approach may be less efficient on current hardware platforms because they are not originally designed for functional programming.
• The functional programming paradigm does not align with the data-oriented needs of the current systems. Such data can be represented through Object-Oriented language.
• Traditional programmers are new to the concept of the functional programming approach.
• The functional language constructs can be less intuitive for programmers making it hard to debug and maintain code.
• The flow of input and output in a system aligns with stream-style processing and may not fit into the data in and results out the approach of functional programming.

Scala overcomes these disadvantages by providing a hybrid environment where you can use Object-oriented features to represent concepts, elements, and functions to express the behavior of a program. So, Scala developers have the advantage of using both the Functional and Object-oriented programming paradigms in their code.
