Clojure vs ReasonML: What are the differences?

Introduction:

Key Differences between Clojure and ReasonML:

1. **Language Paradigm**: Clojure is a functional programming language that runs on the Java Virtual Machine (JVM) and emphasizes immutability and pure functions. On the other hand, ReasonML is a statically-typed functional programming language that compiles to JavaScript and focuses on type safety and interoperability with existing JavaScript code.

2. **Tooling and Ecosystem**: Clojure has a rich ecosystem of libraries and tools built around the JVM, including Leiningen for project management. In contrast, ReasonML integrates well with the wider JavaScript ecosystem and tools like npm, making it easier to work with existing JavaScript libraries and frameworks.

3. **Syntax**: Clojure follows a Lisp-like syntax with a heavy use of parentheses, which can be challenging for new developers to grasp initially. ReasonML, with its syntax inspired by JavaScript, offers a more familiar and readable syntax for developers transitioning from JavaScript.

4. **Error Handling**: Clojure relies heavily on exceptions for error handling, which can sometimes lead to a less predictable code flow. ReasonML, with its emphasis on type safety and pattern matching, provides more reliable and manageable error handling mechanisms.

5. **Concurrency and Parallelism**: Clojure provides powerful abstractions for handling concurrency through its immutable data structures and software transactional memory. ReasonML, while capable of handling concurrency through JavaScript libraries, does not offer built-in support for the same level of concurrency management as Clojure.

6. **Community and Adoption**: Clojure has a strong community of developers who value its simplicity and elegance, making it a popular choice for building robust and scalable applications. ReasonML, being a newer language, is gaining traction among developers looking for type safety and functional programming features in the JavaScript ecosystem. 

In Summary, Clojure and ReasonML differ in their language paradigms, tooling, syntax, error handling approaches, concurrency solutions, and community adoption.

What is Clojure?

Clojure is designed to be a general-purpose language, combining the approachability and interactive development of a scripting language with an efficient and robust infrastructure for multithreaded programming. Clojure is a compiled language - it compiles directly to JVM bytecode, yet remains completely dynamic. Clojure is a dialect of Lisp, and shares with Lisp the code-as-data philosophy and a powerful macro system.

What is ReasonML?

It lets you write simple, fast and quality type safe code while leveraging both the JavaScript & OCaml ecosystems.It is powerful, safe type inference means you rarely have to annotate types, but everything gets checked for you.

What are some alternatives to Clojure and ReasonML?
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.
Haskell
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.
Common Lisp
Lisp was originally created as a practical mathematical notation for computer programs, influenced by the notation of Alonzo Church's lambda calculus. It quickly became the favored programming language for artificial intelligence (AI) research. As one of the earliest programming languages, Lisp pioneered many ideas in computer science, including tree data structures, automatic storage management, dynamic typing, conditionals, higher-order functions, recursion, and the self-hosting compiler. [source: wikipedia]
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.
Julia
Julia is a high-level, high-performance dynamic programming language for technical computing, with syntax that is familiar to users of other technical computing environments. It provides a sophisticated compiler, distributed parallel execution, numerical accuracy, and an extensive mathematical function library.
