When should you use useImperativeHandle?

The useImperativeHandler hook will be used in below cases:

• You want to expose imperative methods from a child component

• Custom input controls exposing focus, clear, or validate methods
• Modal components exposing open() and close() methods
• Scroll containers exposing scrollToTop() or scrollToBottom() methods

• You want to hide internal implementation but provide controlled external access.
• You're building reusable component libraries (e.g., inputs, modals, form controls).
