Project Complete

Your To-Do List is finished.

You started with a prepared interface and progressively connected the application behavior behind it. The final project now combines task management, task details, filtering, search, sorting, persistence, custom modals, drag and drop, data transfer, dark mode, and responsive behavior.

Before publishing or sharing the project, make one last test from a clean page load and confirm that the complete workflow works without errors.

Final checkpoint

If you can add a task, manage it, find it, reorder it, refresh the page without losing it, export it, import it, switch themes, and complete the workflow without browser-native dialogs, your project is ready.

Congratulations — you built a complete To-Do List application with vanilla JavaScript.
