Questions about how to reduce repetition of javascript

About Array Object Creator Prototype and Inheritance?

First, I think it would be good to borrow an object-oriented book written in JS from the library

If you want to make something, do you usually have a blueprint?
ECMA5 JS, of course, doesn't have a class, but in object orientation, 
The class corresponds to a blueprint, and the object is made according to that blueprint

This is how you materialize (instantify) a class to create an object (instance), where the constructor creates the object
 to create such things

The prototype... is a special concept that only JS has You have to dig deep to understand the structure. It's unique 
JS is inherited through a prototype

When inheritance occurs, the child object is a function of the parent object or a property (primitive variable & object & substitution function) 
You will be able to use it 
(On the contrary, the parent object does not access the child object's properties.)

Usually, if you look inside an object, there are prototypes and __proto__
The prototype is the prototype that you own, and there's a constructor inside it, and this is the constructor 

And in order to inherit, you connect your __proto__ to the parent object's prototype

In ECMA5, the function() statement is instantiated by itself (as an object without a class)
