JavaScript Alternatives

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.

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.

WebAssembly or WASM for short, is an open standard and binary instruction format for a stack-based virtual machine. WebAssembly run in all modern web browsers at near-native performance and provides languages such as C/C++ and Rust with a compilation target so that they can run on the web. The language is designed to run alongside JavaScript, allowing both to work together, while simultaneously redefining the web's capability.

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.

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.

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

A free and open general-purpose, object-oriented programming language developed by Ary Borenszweig, Juan Wajnerman, Brian Cardiff and a community with over 300 contributors. Crystal is statically type checked, which means that all code errors will be caught at compile time, rather than fail on runtime. Crystal provides an easy-to-learn syntax similar to Ruby, while at the same time producing performance similar to that of the programming language C.
