Haskell vs JRuby vs Rust: What are the differences?

Syntax and Typing: Haskell is a statically typed language with a strong emphasis on purity and immutability, while JRuby is a dynamically typed language that runs on the Java Virtual Machine (JVM). Rust, on the other hand, is a statically typed language with a focus on memory safety and performance.
Concurrency: Haskell provides powerful concurrency primitives like Software Transactional Memory (STM) and lightweight threads, making it well-suited for concurrent programming. JRuby relies on the Java concurrency model supported by the JVM. Rust emphasizes safe thread communication through ownership and borrowing rules, ensuring memory safety without the need for a garbage collector.
Performance: Rust is known for its high performance and low-level control due to its memory management model. JRuby, being an implementation of Ruby on the JVM, can suffer from slower performance compared to native languages. Haskell, while known for its expressive functional programming capabilities, may not always achieve the same performance levels as languages like Rust.
Ecosystem and Libraries: JRuby benefits from the vast ecosystem of Java libraries and tools available on the JVM, making it easier to integrate with existing Java applications. Haskell has a strong community and growing ecosystem of libraries for functional programming tasks. Rust has a rapidly expanding ecosystem with a focus on safety and performance, especially in systems programming.
Tooling and IDE Support: Rust provides excellent tooling support through its official compiler, Cargo package manager, and IDE plugins like rust-analyzer for features like code completion and syntax highlighting. Haskell has tooling like GHC compiler and Stack build tool but may have a steeper learning curve for beginners. JRuby leverages the tooling provided by the Java ecosystem, such as popular IDEs like IntelliJ IDEA.
Safety and Error Handling: Rust's ownership system ensures memory safety at compile time, catching errors like null pointer dereferencing and data races. Haskell emphasizes purity and immutability to prevent side effects, making it easier to reason about code but potentially leading to performance overhead. JRuby inherits Ruby's focus on developer happiness but may lack the strict safety guarantees of Rust or the functional purity of Haskell.

In Summary, Haskell, JRuby, and Rust differ in syntax and typing, concurrency models, performance characteristics, ecosystem and libraries, tooling support, and safety/error handling approaches.

Detailed Comparison

JRuby	Haskell	Rust
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.	It is a general purpose language that can be used in any domain and use case, it is ideally suited for proprietary business logic and data analysis, fast prototyping and enhancing existing software environments with correct code, performance and scalability.	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.

What are some alternatives to JRuby, Haskell, Rust?

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!

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.
