The function will be assigned the prototype property of the 0bject variety, roughly denoted as Person.prototype = {};
the "prototype" object will be assigned the constructor property with a reference to the function itself, which is conventionally written as
This example is rather conditional and is intended to explain the meaning of manipulation and its order. Thanks to the constructor property, the prototype property of the function, it is possible to form objects by calling another object. "...1" does not have a constructor, therefore, having received a request for this method, the system will search in person1.__proto__. The chain is built as follows:

It's a bit confusing, but that's it. The listing should end by entering the constructor.

When forming a starting object, a prototype is assigned to it with the prototype property of the constructor. Each prototype of this element “=” another and is sent to a single object. If you insert the japan consumer email list original property into prototype, it will necessarily become available to objects of the class.

In this case, any object is named and has a personal speak, and such a quality as talk refers to a single prototype. Any object can access this prototype property without restrictions. And the this determinant does not exclude values ​​and sends a request to the element. When creating classes, it is recommended to place methods as prototype.

Instanceof
This is an operator with the syntax obj <FunctionName>, with an element on one side and a function on the other. This scheme is designed to return true if the element is part of a function.

An object is part of a function when the prototype property is part of a prototype chain link. That is, it looks something like this:
