"Elixir: Dynamic language for high-performance applications"
- Elixir is a dynamic programming language created by Jose Valim in 2012, running on the Erlang Beam virtual machine developed in the 1980s for phone switching demands. It offers a minimal Ruby-inspired syntax, is dynamically typed, compiled to beam bytecode for better performance, and is used by companies like Discord, Motorola, and Pinterest for various applications.
- To start using Elixir, install Erlang and Elixir, create a file with a .exs extension, define variables without type annotations, print output with IO.puts, create atoms as constants, use anonymous functions with the FN keyword, simplify expressions with the Ampersand shorthand, pass values between expressions with the pipe operator, assign variables with the match operator, implement pattern matching for advanced control flow, organize code with modules, and leverage the language's concurrency model for high-performance, fault-tolerant execution through isolated processes communicating via messages.
