Introduction to Redux — Pure Functions, Reducers, and Immutable State

Understand why immutability and pure functions are the foundation of predictable state management — not just good practice. After this lesson you'll write reducers that handle complex state transitions without mutation, build a minimal Store from scratch, and understand exactly what breaks when a reducer isn't pure.
