Getting Started with Elixir

Elixir is a dynamic, functional language designed for building scalable and maintainable applications. It leverages the Erlang VM, known for running low-latency, distributed, and fault-tolerant systems.

Key Features

• Functional Programming: Immutable data and pattern matching
• Scalability: Built on the Erlang VM for concurrent processing
• Fault Tolerance: Supervisor trees and the "let it crash" philosophy
• Developer Productivity: Powerful metaprogramming and a helpful compiler

Basic Syntax

defmodule Greeting do
  def hello(name) do
    "Hello, #{name}!"
  end
end

IO.puts Greeting.hello("World")

Pattern Matching

One of Elixir's most powerful features is pattern matching:

# Assign value
x = 1

# Pattern matching
{a, b, c} = {:hello, "world", 42}

# Pattern matching in function definitions
def process({:ok, result}), do: result
def process({:error, reason}), do: raise(reason)

The Pipe Operator

Elixir's pipe operator (|>) allows for clean, readable code:

"Elixir rocks!"
|> String.upcase()
|> String.split()
|> Enum.count()
