+
+The `title()` method is used to modify the title of the frame. Title is optional.
+
+> **Note:** If you use title method without passing any argument, it will reset the title to default title (Remember: title is optional).
+
+```js
+// modify the title
+const newTitle = 'New Title';
+frame.title(newTitle);
+
+// Reset the title to default
+frame.title();
+```
