-Stores are a state management primitive that provide a centralized location to reduce code redundancy. Unlike [signals](/concepts/signals), which manage a single piece of state and re-render entirely when updated, stores retain fine-grained reactivity by updating only the specific properties that change. They can generate a collection of reactive signals, each tied to a specific property, making them ideal for managing complex state efficiently.
