This is a small React to-do list. The browser mounts the app, where users add or update tasks through the form and view, edit, delete, or complete them in the task list; the app holds task state and displays completed and uncompleted counts. Task data is held in component state, with no persistence or backend shown. The graph reflects the sampled component calls and callbacks; it does not infer additional behavior from the template README.
