SortableJS
SortableJS is a lightweight, touch-friendly JavaScript library for creating sortable lists and grids with drag-and-drop functionality. It enables developers to implement reorderable UI elements without dependencies on jQuery or other frameworks, supporting HTML5 drag-and-drop and touch events. It is commonly used for building interactive interfaces where users can rearrange items, such as in to-do lists, dashboards, or admin panels.
Developers should learn SortableJS when they need to add drag-and-drop sorting to web applications, especially for projects requiring cross-browser compatibility and mobile support without heavy dependencies. It is ideal for use cases like content management systems, kanban boards, or any UI where item ordering is user-configurable, as it simplifies implementation with minimal code and good performance.
