State Management in Elixir: Efficient Fibonacci with Agents

Managing state in a functional, immutable programming language can feel counterintuitive at first. This text-based course guides you through Elixir's powerful concurrency model, showing you how to use Agents to maintain state, implement caching, and dramatically speed up computational tasks like the Fibonacci sequence. You will transition from writing slow, naive recursive functions to deploying highly optimized, concurrent solutions that store and retrieve calculated values on the fly. What you'll learn: - Understand the core principles of state and immutability in Elixir - Configure and spawn Elixir Agents to store and retrieve state across processes - Optimize recursive algorithms using process-based memoization techniques - Apply modern Elixir code conventions, including type specifications and pattern matching - Debug and inspect concurrent state container processes safely This course begins with foundational definitions of functional state and process-based architecture before moving into practical implementation. You will read structured explanations, analyze step-by-step code examples, and practice optimizing algorithms using Elixir's native OTP abstractions. This course is designed for beginner to intermediate Elixir developers who want to understand state management and concurrency. No prior experience with OTP or Agents is required.
