Lifting State Up is a pattern in React where state is moved from child components to their parent component to share state between multiple components.
❓ How is it used?
To lift state up in React, you identify the common ancestor of the components that need access to the shared state. You then move the state up to the nearest common ancestor and pass it down to the child components as props.
Why is it needed?
Lifting State Up promotes better data flow and encapsulation in React applications by centralizing state management in higher-level components. It avoids prop drilling (passing props down multiple levels), improves code maintainability, and simplifies state management.
Examples:
Suppose you have a form component and a list component that both need access to the same data. Instead of maintaining separate state in each component, you lift the shared state up to a common parent component and pass it down to both child components as props.
Lifting State Up is commonly used in scenarios where multiple components need access to the same data or where the state needs to be shared and synchronized across different parts of the application.
