Organize Tasks with a Drag & Drop Kanban Board Organize tasks with a drag-and-drop Kanban board featuring customizable columns and color-coded cards.

The tool's core functionality relies on the React library for managing state and rendering the user interface. It utilizes the `useState` hook to store the board's state as an array of Column objects, each containing an array of Card objects with unique IDs generated using `Date.now()` and a random suffix. The `useCallback` hook is used to memoize functions like `addCard`, which updates the state by adding a new card to the specified column. When a card is dragged and dropped, the tool uses the HTML5 Drag and Drop API to store the column and card IDs in the `dataTransfer` object, allowing it to remove the card from its source column and add it to the destination column.

The tool's rendering process involves mapping over the array of Column objects and creating a separate div element for each column. Inside each column div, it maps over the array of Card objects and creates a draggable div element for each card. When a card is being edited, the tool uses an input field to allow users to update the card's text, and the `saveEdit` function updates the state with the new text. The tool also supports adding new columns and deleting existing ones by updating the state array of Column objects. Additionally, it utilizes CSS classes like `glass-card` and `glass-input` to style the user interface, providing a visually appealing and intuitive experience for users.

The use of React's `useState` and `useCallback` hooks enables efficient management of the tool's state and side effects, while the HTML5 Drag and Drop API provides a seamless user experience for dragging and dropping cards between columns. The tool's data structure, consisting of Column objects with Card arrays, allows for easy manipulation and updating of the board's state, making it a robust and flexible solution for task management and project tracking. By leveraging these technologies, the tool provides a fast and responsive user interface that can handle a large number of cards and columns, making it suitable for a wide range of use cases.
