+```js
+app.get("/rolldice", (req, res) => {
+    let diceVal = Math.floor(Math.random() * 6) + 1;
+    res.render("dice", { num: diceVal });
+});
+```
+
+**Template**
+
+```ejs
+<h1>The random dice value is <%= num %></h1>
+
+<% if (num == 6) { %>
+    <h2>Congratulations, you rolled a 6!</h2>
+<% } %>
+```
+
+### 3. Example: Instagram Profile
+
+**Server**
+
+```js
+app.get("/instagram/:username", (req, res) => {
+    let { username } = req.params;
+    const userData = data[username];
+
+    if (userData) {
+        res.render("instagram", { userData });
+    } else {
+        res.send("Sorry, user not found!");
+    }
+});
+```
+
+**Template**
+
+```ejs
+<h1><%= userData.name %></h1>
+<p>Followers: <%= userData.followers %></p>
+<p>Following: <%= userData.following %></p>
+<hr />
+
+<% for (let post of userData.posts) { %>
+    <img src="<%= post.image %>">
+    <p>Likes: <%= post.likes %></p>
+<% } %>
