 ## Motivation
 
-Proposal motivation
+If i want change some properties inside existed object it will be wieard:
+
+```js
+const user = { name: "user", password: "password", likes: 0, friends: [...] };
+
+const updatedUser = {
+  ...user,
+  friends: user.friends.concat(newFriend),
+  likes: user.likes + 1,
+}
+```
+
+I propose Dart-like Cascade Operator which will be more declarative than previous object update
 
 ## High-level API
 
 ```js
-// example code
+const user = { name: "user", password: "password", likes: 0, friends: [...] };
+
+const updatedUser = user
+  ..friends.concat(newUsser)
+  ..likes += 1;
 ```
