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.
i think becuse to access property in prototype use this keyword and in arrow function this keyword go to global scope this reason arrow function not work but simple function allow this keyword so this property when use in simple function it can access value in prototype
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

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

sir please tell me any javascript book (not beginners book)
I live in india
You are the best
i found when you want to use arrow function in prototype it dosent work you have to notice the Function keyword.
There are some rules in Arrow function
i think becuse to access property in prototype use this keyword and in arrow function this keyword go to global scope this reason arrow function not work but simple function allow this keyword so this property when use in simple function it can access value in prototype
how to get the console tab ?
