There are a number of factors that help to determine which functional language to choose for a given project, starting with strong community support on platforms like StackOverflow and GitHub. Being able to find an answer to a specific challenge in the language — and not having to reinvent the wheel — is a huge productivity boost.
Axon started life as TASER International and builds a range of software and hardware tools designed for use by law enforcement and public safety institutions. Senior Software Engineer Tamas Weisz said his team benefits from bringing a functional programming mindset even when coding in non-functional languages like Java. A large part of the backend services for this system is written in Scala, including real-time information processing from Axon body cameras worn in the field, AI training, analytics, reporting, core evidence workflow and access control logic, as well as services used by other Axon teams such as user and session management.
In particular, lots of our front end JavaScript code is written in a somewhat functional style — we use React, which encourages this style anyway. Headquartered in Los Angeles, the company was one of the earliest app developers on iOS.
Director of Engineering Josh Conner said he generally hires engineers who are new to Scala, and as such must anticipate his staffing needs before they become acute.
Almost all of our ad-serving and data-processing backend services are written in Scala. Those services include everything from garden mulching and lawn mowing to ceiling fan installation and deck repairs. Some of our backend Scala services include our communication platform, which manages email, SMS and web-based chat; our real-time phone call routing platform; our event scheduling system; our file storage platform; our partner-facing API layer; and our project service, which manages the lifecycle of a project between a homeowner and pros.
We love Scala as a general purpose back end language. Estonian software company Nortal builds a wide range of tools and services for enterprise and mid-market clients. The company arrived in the Pacific Northwest with its acquisition of Kirkland-based Dev9 last year, and maintains that office to focus on building custom cloud and software products.
Because Nortal works with a variety of customers, Solutions Architect Nathan Skone said his company must consider the practicality of adopting Scala-based tools within a client organization.
Scala is often a perfect fit for our big data projects. The entry barrier into functional programming as a whole is still surprisingly high. Most developers have had very limited exposure to proper functional programming and are hesitant to explore its benefits. We have been lucky to have a group of developers and stakeholders that were excited about the journey, and convinced of the eventual benefits. The Scala community has created a rich set of tooling to ensure adherence to proper conventions and quality guidelines.
Our team loves how concise and compact code written in Scala can be. Concepts that would otherwise need to be pulled into a separate method can often be articulated by a single line of functional code.
The conciseness of the language comes to mind as one of the major benefits. Being able to express large algorithmic meaning and not having to write repetitive boilerplate code makes teams productive.

View code. Scalaz Scalaz is a Scala library for functional programming. In a dynamic language, you can never be sure that your code is sufficiently bug-free and robust until you actually run it in a wide range of scenarios.
This can lead to potentially serious defects in code that never get realized until the code is in production. Hopefully, this article stacks up Java vs. Scala enough to give you a preliminary sense of the power and capabilities of Scala and whets your appetite for learning the language. Scala is a powerful high-level programming language that incorporates object-oriented and functional programming.
It's a type-safe language that relies on the JVM runtime. A lot of things, ranging from machine learning to web apps. As a high-level general purpose language, Scala boasts an extensive range of possible applications. Scala allows developers to make good use of standard JVM features and Java libraries. However, if you have no Java experience, you will need to learn the basics. Familiarity with functional programming languages will help as well.
It's also used in finance, by the likes of Bloomberg and UBS. This is a subject of no small debate. Subscription implies consent to our privacy policy. Thank you!

Parallelism is very tricky to get right, and Scala offers a number of libraries which make this task easier, by building abstractions. Modeling typical business applications can also be taken to another level, using the available Scala features.
Here however the complexity is of a different kind. With distributed systems, the complexity was technical. With business applications, the complexity is in the problem domain itself. As a side note, Scala is often said to have a large number of features, thus making the language complex. However, they all can be combined with each other, which gives the languages its flexibility.
Most of the novel work that you see out there is some form of combining higher-kinded types, implicit parameters and subtyping. Hence while the number of core features is small comparing grammar size , the language is simpler than Kotlin, Java or Swift!
As competent, responsible software engineers, we are more than capable to choose how to best solve a specific problem. There are two main reasons:. What are typeclasses? They play a role similar to design patterns in Java, but are more flexible and easier to use once the idea sinks in.
And what about type constructors? You might have a Option[String] , or a Future[Int].
