Elixir is a functional programming language built on top of the Erlang virtual machine. It provides a scalable and fault-tolerant approach to building distributed systems. Elixir is a great choice for building real-time applications, such as chat systems, gaming servers, and more.
To get started with Elixir, you'll need to install the language and its dependencies on your machine. You can do this by following the installation instructions on the Elixir website: https://elixir-lang.org/install.html.
Once you have Elixir installed, you can start experimenting with the language. Elixir has a built-in interactive shell called iex
that you can use to evaluate expressions and test out code. To start iex
, simply open up a terminal and run iex
.
$ iex
Erlang/OTP 23 [erts-11.1.7] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1]
Interactive Elixir (1.11.3) - press Ctrl+C to exit (type h() ENTER for help)

Elixir has a number of features that make it a powerful language for building real-time applications:
Elixir makes it easy to write concurrent and parallel programs. Its lightweight processes, called "actors," provide a scalable way to handle many concurrent connections. Elixir's processes are isolated from each other and communicate through message passing, which makes it easy to reason about your code and build reliable systems.
Elixir is a functional programming language, which means that functions are first-class objects in the language. You can pass functions as arguments to other functions, and use higher-order functions to build complex data structures. Elixir also supports pattern matching, which is a powerful way to manipulate data and control the flow of your program.
Elixir has a powerful macro system that allows you to write code that generates other code. This makes it easy to write libraries and frameworks that can generate boilerplate code for you. Elixir also provides metaprogramming capabilities, which allow you to modify the behavior of the language at runtime.
There are many resources available for learning Elixir, including books, online courses, and documentation. Here are a few resources to get you started:
