Hi ! ,
can you tell me why you wrote like this :
not just : Teacher.prototype = Person.prototype

not just : Teacher.prototype = Person.prototype

Hello @Mohamed_Iyed and welcome to the community 
From Object.create():
The
Object.create()method creates a new object, using an existing object as the prototype of the newly created object.
With the assignment in your screenshot we achieve that Teacher.prototype has Person.prototype as its prototype. In other words: Teacher.prototype inherits from Person.prototype.
If we are just doing Teacher.prototype = Person.prototype, Teacher.prototype is the same as Person.prototype and we have no inheritance.
I hope that helps. Feel free to ask more questions if you like
Have a nice day,
Michael
