How do you implement drag and drop in React?

Short answer: You can use libraries like react-dnd or react-beautiful-dnd for drag-and-drop functionality. Example with react-beautiful-dnd: npm install react-beautiful-dnd import { DragDropContext, Droppable, Draggable } from 'react-beautiful-dnd'; function App() { const items = ['item1', 'item2', 'item3'];

Example code

return ( <DragDropContext onDragEnd={() => {}}> <Droppable droppableId="droppable"> {(provided) => ( <ul ref={provided.innerRef} {...provided.droppableProps}> {items.map((item, index) => ( <Draggable key={item} draggableId={item} index={index}> {(provided) => ( <li ref={provided.innerRef} {...provided.draggableProps} {...provided.dragHandleProps} {item} </li> )} </Draggable> ))} {provided.placeholder} </ul> )} </Droppable> </DragDropContext> ); }

Real-world example (ShopNest)

ShopNest’s storefront is React: components for ProductCard, CartDrawer, and CheckoutForm, with hooks for local UI state.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
