+### 2.1 Use Closure instead of `Callback`
+
+You can use a Rust closure `Fn(MouseEvent)` directly instead of `Callback`:
+
+```rust
+#[component]
+pub fn App() -> impl IntoView {
+    let (toggled, set_toggled) = create_signal(false);
+    view! {
+        <p>"Toggled? " {toggled}</p>
+        <ButtonB on_click=move |_| set_toggled.update(|value| *value = !*value)/>
+    }
+}
+

+pub fn ButtonB(#[prop(into)] on_click: Callback<MouseEvent>) -> impl IntoView

+        <button on:click=on_click>
+            "Toggle"
+        </button>
+    }
+}
+```
+
+The code is very similar in this case. On more advanced use-cases using a
+closure might require some cloning compared to using a `Callback`.
+
