Clojure vs JRuby vs JavaScript: What are the differences?

Data Structures: Clojure provides immutable data structures by default, which ensures thread safety and easier state management, while JRuby and JavaScript primarily offer mutable data structures, which can introduce concurrency issues and make state management more complex.
Concurrency: Clojure has built-in support for managing concurrency through the use of software transactional memory (STM), making it easier to write multi-threaded and concurrent programs compared to JRuby and JavaScript, which often require additional libraries or frameworks for handling concurrency effectively.
Functional Programming: Clojure is a functional programming language that encourages immutability, higher-order functions, and pure functions, while JRuby and JavaScript support functional programming to some extent but are more widely used for object-oriented programming paradigms.
Syntax: Clojure's syntax is heavily influenced by Lisp and uses a minimalist approach with parentheses for function calls and data structures, which can be seen as more concise but may require a learning curve for developers not familiar with Lisp-like languages, whereas JRuby and JavaScript have more conventional C-like syntax that is more widely adopted and understood.
Interoperability: JRuby enables seamless integration with Java libraries and frameworks, allowing developers to leverage existing Java codebases, whereas Clojure has similar interoperability with Java but offers more functional programming features, and JavaScript can also interact with Java through various means, but the integration might not be as seamless as in JRuby.
Community and Ecosystem: JavaScript has a vast and diverse community with extensive libraries and frameworks for web development, while Clojure and JRuby have smaller but active communities with strong support for specific use cases such as functional programming (Clojure) and Ruby-based applications (JRuby).

In Summary, Clojure distinguishes itself with immutable data structures and strong support for functional programming, while JRuby excels in Java interoperability, and JavaScript is widely known for its extensive ecosystem and community support.

Detailed Comparison

Clojure	JRuby	JavaScript
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.	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.	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.

What are some alternatives to Clojure, JRuby, JavaScript?

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.

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.
