Go vs JRuby vs Scala: What are the differences?

Introduction: When comparing Go, JRuby, and Scala, each programming language has its own unique set of features and capabilities. Understanding the key differences between these languages can help developers choose the right tool for their specific use case.

Concurrency Model: Go's concurrency model is based on goroutines and channels, making it easier to write concurrent programs compared to JRuby and Scala. Goroutines are lightweight threads managed by the Go runtime, allowing developers to run thousands of them concurrently. On the other hand, JRuby and Scala rely on the Java Virtual Machine (JVM) for concurrency, which can be more complex and prone to errors.
Type System: Scala is a statically typed language that offers a powerful type system with strong type interference capabilities, ensuring better compile-time error checking and code safety. In contrast, both Go and JRuby are dynamically typed languages, allowing for more flexibility but potentially leading to runtime errors due to the lack of strict type checking.
Performance: Go is known for its high performance and efficiency, making it a popular choice for building high-performance applications. JRuby, being an implementation of Ruby on the JVM, typically offers slower performance compared to Go. Scala, being a statically typed language, can also offer good performance but might not match Go's efficiency in certain scenarios.
Tooling and Ecosystem: Go has a robust standard library and tooling support, making it easy for developers to build and maintain their applications. JRuby benefits from the rich ecosystem of libraries available in the Ruby community, but it may lack some of the performance optimizations found in Go. Scala, being a language that runs on the JVM, can leverage the vast array of Java libraries and tools, providing developers with a wide range of options.
Community and Adoption: Go has gained popularity in recent years, with a growing community of developers and strong industry support from companies like Google. JRuby has a dedicated community of Ruby developers but may not have the same level of adoption as Go. Scala, while popular in the Java ecosystem, might not be as widely adopted as Go or have the same level of community support.

In Summary, understanding the key differences in concurrency model, type system, performance, tooling and ecosystem, as well as community adoption, can help developers choose between Go, JRuby, and Scala for their specific project requirements.

Advice on Golang, Scala, JRuby

Decided

When developing a new blockchain, we as a team chose Go lang over Java and other candidates, due to Go being (a) natively suited to concurrency - there are primitives in the language itself (goroutines, channels) that really help with reasoning about concurrency (b) super fast - build time, running, testing are all much faster that Java, this gives a far superior developer experience (c) shorter and stricter than Java - code is much shorter (less verbose), and there is usually one good way to do things, and even the code formatter that is bundled with Go is very opinionated - over a short time this makes reading other people's code far smoother than having to deal with different styles.

You should be aware that Go presently (v1.13) lacks Generics.

We decided to use python to write our ETLs and import them into metabase via a lambda. Before python we tried using Go, but overall go was way more verbose than Python when writing the ETLs. Go also had some issues managing memory when using the S3 upload manager library. This was a deal breaker for us that made us switch to Python.

In the end the solution was much cleaner and maintainable.

PHP is easy to learn and you can get up and running in no time, available on almost all hosting providers and you can find developers easily. It has some great frameworks for building your backend like Symfony and Laravel. However, it can be challenging when running an enterprise and needs some adjustments, very recommended for starting a new project or startup.

Detailed Comparison

Golang	Scala	JRuby
Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.	Scala is an acronym for “Scalable Language”. This means that Scala grows with you. You can play with it by typing one-line expressions and observing the results. But you can also rely on it for large mission critical systems, as many companies, including Twitter, LinkedIn, or Intel do. To some, Scala feels like a scripting language. Its syntax is concise and low ceremony; its types get out of the way because the compiler can infer them.	JRuby is the effort to recreate the Ruby (http://www.ruby-lang.org) interpreter in Java. The Java version is tightly integrated with Java to allow both to script any Java class and to embed the interpreter into any Java application. See the docs directory for more information.

What are some alternatives to Golang, Scala, JRuby?

JavaScript

JavaScript is most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic,and supports object-oriented, imperative, and functional programming styles.

Python

Python is a general purpose programming language created by Guido Van Rossum. Python is most praised for its elegant syntax and readable code, if you are just beginning your programming career python suits you best.

PHP

Fast, flexible and pragmatic, PHP powers everything from your blog to the most popular websites in the world.

Ruby

Ruby is a language of careful balance. Its creator, Yukihiro “Matz” Matsumoto, blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming.

Java

Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!

HTML5

HTML5 is a core technology markup language of the Internet used for structuring and presenting content for the World Wide Web. As of October 2014 this is the final and complete fifth revision of the HTML standard of the World Wide Web Consortium (W3C). The previous version, HTML 4, was standardised in 1997.

C#

C# (pronounced "See Sharp") is a simple, modern, object-oriented, and type-safe programming language. C# has its roots in the C family of languages and will be immediately familiar to C, C++, Java, and JavaScript programmers.

Elixir

Elixir leverages the Erlang VM, known for running low-latency, distributed and fault-tolerant systems, while also being successfully used in web development and the embedded software domain.

Swift

Writing code is interactive and fun, the syntax is concise yet expressive, and apps run lightning-fast. Swift is ready for your next iOS and OS X project — or for addition into your current app — because Swift code works side-by-side with Objective-C.

Rust

Rust is a systems programming language that combines strong compile-time correctness guarantees with fast performance. It improves upon the ideas of other systems languages like C++ by providing guaranteed memory safety (no crashes, no data races) and complete control over the lifecycle of memory.
