Elixir is a functional, concurrent, high-level general-purpose programming language that runs on the BEAM virtual machine, which is also used to implement the Erlang programming language. Elixir builds on top of Erlang and shares the same abstractions for building distributed, fault-tolerant applications. Elixir also provides tooling and an extensible design. The latter is supported by compile-time metaprogramming with macros and polymorphism via protocols.
The community organizes yearly events in the United States, Europe, and Japan, as well as minor local events and conferences.
José Valim is the creator of the Elixir programming language, a research and development project created at Plataformatec. His goals were to enable higher extensibility and productivity in the Erlang VM while maintaining compatibility with Erlang's ecosystem.
Elixir was aimed at large-scale sites and apps. Elixir uses features of Ruby, Erlang, and Clojure to develop a "high-concurrency" and "low-latency" language. Elixir was designed to handle large data volumes. Elixir is used in the telecommunication, eCommerce, and finance industries.
On July 12, 2018, Honeypot released a mini-documentary on Elixir.
Each of the minor versions supports a specific range of Erlang/OTP versions. The current stable release version is .
Compiles to bytecode for the BEAM virtual machine of Erlang. Full interoperability with Erlang code, without runtime impact.
Scalability and fault-tolerance, thanks to Erlang's lightweight concurrency mechanisms
Built-in tooling for managing dependencies, code compilation, running tests, formatting code, remote debugging and more.
An interactive REPL inside running programs, including Phoenix web servers, with code reloading and access to internal state
Everything is an expression
Pattern matching to promote assertive code
Type hints for static analysis tools
Immutable data, with an emphasis, like other functional languages, on recursion and higher-order functions instead of side-effect-based looping
Shared nothing concurrent programming via message passing (actor model)
Lazy and async collections with streams
Railway oriented programming via the with construct
Hygienic metaprogramming by direct access to the abstract syntax tree (AST).
