Introduction to Processes

Coming Soon

This lesson introduces Erlang’s revolutionary process model - lightweight, isolated processes that communicate through message passing. You’ll learn how to:

• Create and manage Erlang processes
• Understand process isolation and fault containment
• Implement the actor model for concurrent programming
• Use spawn, self, and process identifiers (PIDs)
• Build your first concurrent chat server components

What You’ll Build

By the end of this lesson, you’ll have implemented:

• Basic process creation and management
• Simple message passing between processes
• Process monitoring and lifecycle management
• A foundation for concurrent chat server architecture
• Your first actor-based components

Key Concepts Preview

% Creating processes
Pid = spawn(fun() -> chat_user_process() end),
Pid ! {message, "Hello from another process"}.

% Process isolation
self() ! {internal_message, data}.

This lesson builds on the error handling patterns from Lesson 6 and prepares you for the inter-process communication we’ll explore in Lesson 8.
