<h2>📝 Cosa Devi Fare</h2>
<p style="margin-bottom: 15px;"><strong>Questa è l'esercitazione finale!</strong> Devi implementare TUTTE le operazioni CRUD:</p>
<h3>1️⃣ Carica TODO (GET)</h3>
<ul style="margin-left: 20px; margin-bottom: 15px;">
<li>Fai una GET a <code>/todos?userId={id}</code> per ottenere i TODO dell'utente</li>
<li>Visualizza la lista</li>
</ul>
<h3>2️⃣ Aggiungi TODO (POST)</h3>
<ul style="margin-left: 20px; margin-bottom: 15px;">
<li>Fai una POST a <code>/todos</code> con: <code>{userId, titolo, completato: false}</code></li>
<li>Ricarica la lista</li>
</ul>
<h3>3️⃣ Modifica TODO (PUT)</h3>
<ul style="margin-left: 20px; margin-bottom: 15px;">
<li>Fai una PUT a <code>/todos/{id}</code> con: <code>{completato: !currentValue}</code></li>
<li>Aggiorna la lista</li>
</ul>
<h3>4️⃣ Elimina TODO (DELETE)</h3>
<ul style="margin-left: 20px; margin-bottom: 15px;">
<li>Fai una DELETE a <code>/todos/{id}</code></li>
<li>Rimuovi dalla lista</li>
</ul>
<div class="hint">
<strong>💡 Struttura del codice:</strong>
<pre>// Funzioni che devi implementare:
loadUserTodos(userId) // GET
addTodo() // POST
toggleTodo(id, current) // PUT
deleteTodo(id) // DELETE
displayTodos(todos) // Visualizza (già fatto)</pre>
</div>
<div class="challenge">
<strong>🎯 Bonus Challenge:</strong>
<p>Aggiungi un riepilogo: quanti TODO sono completati vs quanti rimangono?</p>
</div>
</div>
