+
+const nestedObject = ref({ foo: { bar: { deep: 5 } } })
+
+watchDeep(nestedObject, (updated) => {
+  console.log(updated)
+})
+
+onMounted(() => {
+  nestedObject.value.foo.bar.deep = 10
+})
+```
+
+## Type Declarations
+
+```ts
+export declare function watchDeep<
+  T extends Readonly<MultiWatchSources>,
+  Immediate extends Readonly<boolean> = false,
+>(
+  source: [...T],
+  cb: WatchCallback<MapSources<T>, MapOldSources<T, Immediate>>,

+export declare function watchDeep<
+  T extends object,
+  Immediate extends Readonly<boolean> = false,
