 What `class User {...}` construct really does is:
-1. Creates a function named `User`, that becomes the result of the class declaration.
-    - The function code is taken from the `constructor` method (assumed empty if we don't write such method).
-3. Stores all methods, such as `sayHi`, in `User.prototype`.

+1. Creates a function named `User`, that becomes the result of the class declaration. The function code is taken from the `constructor` method (assumed empty if we don't write such method).
+2. Stores all methods, such as `sayHi`, in `User.prototype`.
 
 Afterwards, for new objects, when we call a method, it's taken from the prototype, just as  described in the chapter <info:function-prototype>. So a `new User` object has access to class methods.
