A modern, dynamic, and functional dialect of the Lisp and programming language that targets the JVM (Java Virtual Machine). Clojure is a compiled language, yet remains completely dynamic as it combines the approachability and interactive development of a scripting language with an efficient and robust infrastructure for multithreaded programming. The development of Clojure is completely community-driven, while being overseen by its creator Rich Hickey.

A family of programming languages dating back to 1958. Lisp is the second-oldest high-level programming language in widespread use today.

AssemblyScript is a language designed for WebAssembly. AssemblyScript targets WebAssembly's feature set specifically, giving developers low-level control over their code. If you are familiar with TypeScript you will feel right at home as AssemblyScript is a variant of TypeScript that makes it easy to compile to WebAssembly without learning a new language.

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.

NativeScript is an open-source framework that you can use to develop mobile apps on the Apple iOS and Android platforms. The framework is developed and released by Progress, a software development company providing a wide range of SaaS-based products. NativeScript apps are built using JavaScript, or by using any programming language that transpiles to JavaScript, such as TypeScript.

TypeScript is a free and open-source programming language created by Microsoft. The language is a strict syntactical superset of JavaScript and redefines the way developer writes JavaScript-based web applications and software by adding optional static typing in the mix. TypeScript is designed specifically for development of large-scale applications with a need to transcompile into JavaScript.

JerryScript is a lightweight JavaScript engine for resource-constrained devices such as microcontrollers. It can run on devices with less than 64 KB of RAM and less than 200 KB of flash memory.

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.

PHP is a popular free and open-source general-purpose scripting language. The language was created by Danish-Canadian programmer Rasmus Lerdorf in 1994. PHP is fast, flexible and pragmatic and is especially suited to web development. It is utilised by individual developers and large corporations like facebook, where it powers backend services.

Perl is a family high-level, general-purpose, interpreted, dynamic programming languages. The project is open-source and has been in community development for over 30 years. Perl is a highly capable language and feature rich language with over 25,000 community created extensions.

A dynamic, functional programming language that tuns on top of the Erlang Virtual Machine. A VM known for running low-latency, distributed and fault-tolerant systems. Elixir provides productive tooling and an extensible design perfect for building concurrent applications for critical infrastructure

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.
