Lifting State Up

Reading Material & Notes

Lifting State Up

Lifting state up means moving shared state to the closest common parent component so that multiple child components can use the same data.

Why Lift State?

Share data between components.
Keep a single source of truth.
Coordinate related components.
Reduce duplicated state.

This pattern is commonly used when sibling components need to work with the same data.
