JavaScript is a scripting or programming language that conforms to the ECMAScript specification. The language is mainly used to create complex features for web pages, but is also used other software project. Javascript has curly-bracket syntax, dynamic typing, prototype-based object-orientation, and first-class functions and is mostly just-in-time compiled.

An object-oriented, high-level, general-purpose programming language with an easy-to-learn syntax. Python was first released in 1991 by Guido van Rossum with a design philosophy that emphasises code readability. Today Python is one of the most widely used programming languages where it is used in everything from data science, machine learning and AI to modern web, mobile and desktop applications.

A general-purpose, concurrent, functional programming language used to build massively scalable soft real-time systems with requirements on high availability. Erlang comes bundled with the OTP, the Open Telecom Platform which is a runtime system first developed by Ericsson to handle the Swedish telecom infrastructure in the early 80's. The term Erlang and OTP is today used interchangeably and includes the runtime, the language and ready-to-use components built specifically for the ecosystem. To this day, Erlang is used in various sectors and applications like telecoms, banking, e-commerce, computer telephony and instant messaging. As the language is suitable for critical infrastructure and applications that requires high availability and real-time features, running at scale.

Ruby is a free and open-source interpreted, high-level, general-purpose programming language. The language was created by Yukihiro "Matz" Matsumoto from Japan in the mid-1990s. Today, Ruby has a friendly and growing community from all over the world and is openly developed and maintained. According to its creator Yukihiro, the language share many similarities with Perl, Smalltalk, Eiffel, Ada, Basic, and Lisp, all of which Ruby was influenced by.

ClojureScript is a compiler for Clojure that targets JavaScript. It emits JavaScript code which is compatible with the advanced compilation mode of the Google Closure optimizing compiler. With ClojureScript, you write browser and web-based applications using Clojure and the REPL, allowing you to write the same Lisp syntax that you are used to in the Clojure ecosystem.
