Elixir is a functional, concurrent, and general-purpose programming language that runs on the Erlang Virtual Machine (BEAM). It is known for its scalability, fault-tolerance, and robustness. Elixir is designed to build reliable and distributed systems, making it a popular choice for developing real-time web applications, networked systems, and distributed applications. It provides an elegant syntax and comprehensive tooling, making it easier for developers to write maintainable and efficient code. Used for building scalable and fault-tolerant applications, real-time web applications, networked systems, distributed systems, and backend services.
