+To make an object immutable, you can use `Object.freeze()` method. It prevents the modification of existing property values and prevents the addition of new properties.
+
+```js
+const roadmap = {
+  name: 'JavaScript',
+};
+
+Object.freeze(roadmap);
+
+roadmap.name = 'JavaScript Roadmap'; // throws an error in strict mode
+console.log(roadmap.name); // JavaScript
+```
