Started learning Java 2 weeks ago. Halfway through this video and I can understand this so much better than if I didn’t understand objects and inheritance. Thank you

Comment made after watching a useful video so I don't forget what it was about #3.

Prototype is useful to add new methods or properties to an object, so you don't modify the object itself.

This isnt inheritance, this is dependency injection handled through reflection.

10:46 you are not changing the prototype's property age but you are changing the whole prototype object by using {age:52}

if you did Person.prototype.age=52 then all objects new ones and old ones will have same age value . The behaviour in your case Is because of old objects still pointing at the old prototype object which had the age value as 25 . And when you changed the whole prototype object on line 5 any object declared after that will have this other prototype object .


Summary changing prototype object and changing prototype object's property have different behaviours
