OCaml vs Ruby: What are the differences?

Introduction:

When discussing the differences between OCaml and Ruby, it is important to understand the key distinctions that set these two programming languages apart.

Type System: One significant difference between OCaml and Ruby lies in their type systems. OCaml is statically typed, meaning that the type of every expression is known at compile time, allowing for more rigorous error checking and increased efficiency. On the other hand, Ruby is dynamically typed, which means that types are checked at runtime, providing more flexibility but potentially introducing more errors during execution.
Functional vs. Object-Oriented Paradigm: OCaml is a functional programming language that emphasizes immutable data and pure functions, enabling developers to write concise and declarative code. In contrast, Ruby is an object-oriented language that focuses on objects and classes, allowing for straightforward object manipulation and inheritance. The difference in paradigms can affect how developers approach problem-solving and code organization.
Performance: OCaml typically offers better performance compared to Ruby due to its static typing and compile-time optimizations. The statically typed nature of OCaml allows for more efficient memory allocation and management, leading to faster execution speeds for certain tasks. Ruby, being dynamically typed and interpreted, may have slower performance in some scenarios, especially when dealing with computationally intensive operations.
Concurrency and Parallelism: OCaml provides robust support for concurrency and parallelism through features such as lightweight threads, asynchronous I/O, and powerful libraries like Async and Lwt. These capabilities allow for efficient utilization of multicore processors and scalable concurrent programming. In contrast, Ruby's concurrency options are more limited, with the Global Interpreter Lock (GIL) restricting parallelism in CRuby implementations.
Community and Ecosystem: The communities surrounding OCaml and Ruby differ in terms of size, focus, and available resources. The OCaml community tends to be smaller but tightly knit, with a strong emphasis on academic research, formal verification, and functional programming principles. In comparison, the Ruby community is larger, more diverse, and often driven by web development, open-source contributions, and community-driven projects like Ruby on Rails.
Learning Curve and Adoption: OCaml is often considered more challenging to learn for beginners, as its functional programming paradigm and type system can be unfamiliar to those coming from more traditional, imperative languages. Ruby, with its emphasis on readability and developer satisfaction, is generally viewed as more approachable and beginner-friendly. This difference in learning curve can influence the adoption rate of each language in different contexts and industries.

In Summary, the key differences between OCaml and Ruby encompass their type systems, programming paradigms, performance characteristics, concurrency support, community ecosystems, and learning curve.

In December we successfully flipped around half a billion monthly API requests from our Ruby on Rails application to some new Python 3 applications. Our Head of Engineering has written a great article as to why we decided to transition from Ruby on Rails to Python 3! Read more about it in the link below.

Decided

In 2015 as Xelex Digital was paving a new technology path, moving from ASP.NET web services and web applications, we knew that we wanted to move to a more modular decoupled base of applications centered around REST APIs.

To that end we spent several months studying API design patterns and decided to use our own adaptation of CRUD, specifically a SCRUD pattern that elevates query params to a more central role via the Search action.

Once we nailed down the API design pattern it was time to decide what language(s) our new APIs would be built upon. Our team has always been driven by the right tool for the job rather than what we know best. That said, in balancing practicality we chose to focus on 3 options that our team had deep experience with and knew the pros and cons of.

For us it came down to C#, JavaScript, and Ruby. At the time we owned our infrastructure, racks in cages, that were all loaded with Windows. We were also at a point that we were using that infrastructure to it's fullest and could not afford additional servers running Linux. That's a long way of saying we decided against Ruby as it doesn't play nice on Windows.

That left us with two options. We went a very unconventional route for deciding between the two. We built MVP APIs on both. The interfaces were identical and interchangeable. What we found was easily quantifiable differences.

We were able to iterate on our Node based APIs much more rapidly than we were our C# APIs. For us this was owed to the community coupled with the extremely dynamic nature of JS. There were tradeoffs we considered, latency was (acceptably) higher on requests to our Node APIs. No strong types to protect us from ourselves, but we've rarely found that to be an issue.

As such we decided to commit resources to our Node APIs and push it out as the core brain of our new system. We haven't looked back since. It has consistently met our needs, scaling with us, getting better with time as continually pour into and expand our capabilities.

Decided

When I was evaluating languages to write this app in, I considered either Python or JavaScript at the time. I find Ruby very pleasant to read and write, and the Ruby community has built out a wide variety of test tools and approaches, helping e deliver better software faster. Along with Rails, and the Ruby-first Heroku support, this was an easy decision.

Ruby	OCaml
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.	It is an industrial strength programming language supporting functional, imperative and object-oriented styles. It is the technology of choice in companies where a single mistake can cost millions and speed matters,

What are some alternatives to Ruby, OCaml?

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.

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!

Golang

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.

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.

Scala

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.

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.
