Course Introduction：The key to implementing the sortable list lies in the HTML5 drag and drop API. The following points should be noted: 1. Set the draggable attribute to make the elements draggable and prevent the default behavior of the dragover to allow placement; 2. Listen to dragstart to record drag data, and update the DOM structure when dropping; 3. Use the dragover event to judge the insertion position in combination with coordinates to realize the sorting logic; 4. Add style optimization experience and handle mobile compatibility issues.

Course Introduction：The working principle of HTMLDragandDrop API includes the following steps: 1. Set elements to be dragged, set draggable="true" and handle dragstart events to define the behavior at the beginning of the drag; 2. Process events during the dragging process, such as dragover and dragleave to control the drag interaction; 3. Get data in the drop event and perform placement operations, while canceling the default behavior to allow placement; 4. Add visual feedback to improve the user experience. Common use cases include list sorting, file uploading and building kanban interfaces. When using it, you need to pay attention to calling e.preventDefault(), controlling effects and avoiding performance-affecting operations.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
