Correct Prototype Chain In Console (with Object Inheritance)

Forgive me for being bothered by something that works, yet not showing up 'as expected' on the console. Consider the following code: function Person() {}; Person.prototype.PersonAc

Solution 1:

This will do it by setting the constructor back to what it's supposed to be and using Object.create() for the prototype:

functionMammal() {};
Mammal.prototype.MammalAction = function() {}

functionPerson() {};
Person.prototype = Object.create(Mammal.prototype);
Person.prototype.PersonAction = function() {}
Person.prototype.constructor = Person;

console.log( newPerson() );

It gives you this in Chrome:

Person {PersonAction: function, constructor: function, MammalAction: function}
    __proto__: PersonPersonAction: function () {}
        constructor: functionPerson() {}
       __proto__: MammalMammalAction: function () {}
           constructor: functionMammal() {}
           __proto__: Object

Solution 2:

It is correct, you set Person prototype with an instance of mammal and added a property personaction.

I assume personaction is not a constructor so it should not be capitalizes, its better to use object.create instead of creating an instance of parent to set the prototype part of inheritance.
