Part One | Functional Programming Through Elixir: Immutability vs Mutable State
The Foundation of Functional Programming
If you’re coming from an object-oriented programming background, one of the most fundamental shifts in thinking when learning functional programming is immutability. In Elixir and other functional languages, data never changes once it’s created. This might sound limiting at first, but it’s actually a superpower that unlocks predictability, thread safety, and easier debugging.
This is the first post in a series exploring functional programming concepts through Elixir, aimed at developers transitioning from OOP paradigms.
