At Google I/O 2017, Kotlin was announced as to official development and programming language for Android. As it became the third language to be fully supported by the platform with Java and C++. However, Kotlin can also be used cross-paltform for native, server-side and web development as well as for data science projects. The language is statically typed and general-purpose, and is designed from the bottom up to increase developer happiness.

Haskell is a free and open-source purely-functional programming language. The language has been around since the 1990's and has pioneered a number of advanced programming language features such as type classes, which enable type-safe operator overloading. Haskell is an open-source project of more than twenty years of scientific research and provides built-in concurrency and parallelism, debuggers, profilers and rich libraries that can be used to build robust applications while following functional programming patterns.

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.
