React DnD (Drag and Drop) is a popular library for building complex and customizable drag-and-drop interfaces in React applications. It provides a set of React components and utilities that make it easy to create draggable and droppable elements, defines the behaviour of drag-and-drop events, and handles the data transfer between them.
React DnD is designed to work with the HTML5 drag-and-drop API and supports touch devices, making it ideal for building modern web applications with rich user interactions. With React DnD, you can create a wide range of drag-and-drop scenarios, from the simple reordering of items to more complex interactions like dragging elements between containers or snapping items to a grid.
React DnD is built on top of the popular Redux library and uses a similar architecture to manage the state of drag-and-drop interactions. It also provides a number of higher-order components (HOCs) that can be used to wrap your existing React components and add drag-and-drop behaviour to them.
Overall, React DnD is a powerful and flexible library that can help you build dynamic and engaging user interfaces in your React applications.
