    What is Redux?

    Redux is a state management library used for predictable global state.

    Especially useful for:

    • Large applications

    • Complex data flow

    • Multiple components sharing state

    Core Redux Concepts

    Redux works on three main principles:

    Store

    • Holds the entire application state

    • Single source of truth

    Actions

    • Plain JavaScript objects

    • Describe what happened

{ type: "ADD_TODO" }

  • Reducers

    • Pure functions

    Decide how state changes

(state, action) => newState
