To-Do List

Keep a list, tick things off, and have it still be there after a refresh.

The classic first app. Add items, check them done, delete them — and because it saves to your browser, your list survives a page reload. You'll meet arrays, re-rendering, and localStorage.

What's inside

• Add, complete and delete items
• State lives in an array; the screen re-renders from it
• Saves to localStorage so it persists across refreshes
• A live "items left" counter
• Light & dark mode, no dependencies
