Introduction to Elixir

[Jessica Brown]

Elixir is a dynamic, functional programming language designed for building scalable and maintainable applications. Running on the Erlang VM (BEAM), Elixir excels at handling concurrent and distributed systems, making it a popular choice for web development and real-time applications.

What is Elixir Best Used For?

• Developing scalable and fault-tolerant systems.
• Building real-time applications like chat systems or multiplayer games.
• Handling concurrent and distributed systems efficiently.
• Creating maintainable, functional codebases with modern syntax.

Example Elixir Script

This script demonstrates variables, a loop, and output.

# Define a variable
greeting = "Hello, Elixir Programmer!"
count = 5

# Display greeting
IO.puts(greeting)

# Loop through numbers 1 to count
for i <- 1..count do
  IO.puts("Iteration: #{i}")
end

# Print completion message
IO.puts("Loop completed! Total iterations: #{count}")

Explanation:

1. Variables: greeting holds a string message, and count specifies the loop range.
2. Loop: The for loop iterates through the range 1..count and outputs each iteration using string interpolation.
3. Output: The script prints the greeting, each iteration, and a completion message.

Sample Output:

Hello, Elixir Programmer!
Iteration: 1
Iteration: 2
Iteration: 3
Iteration: 4
Iteration: 5
Loop completed! Total iterations: 5
