 ## Motivation
 
-Proposal motivation
+Sometimes to prevent object and array changes we should to use `Object.freeze`, but the method very slow, so i propose readonly structure which will be constant by default
 
 ## High-level API
 
 ```js
-// example code
+const USER_STATUSES = new ReadOnly([
+ "banned",
+ "active",
+ "deleted"
+]);
+
+USER_STATUS[0] = "something" // Throw type error
 ```
