Does DOM API use constructors and prototypes in creating/manipulating nodes?

I'm trying to understand DOM API through OOP frame of mind. Since DOM API uses properties and methods that are built into the browser and document in, say, document.createElement is an instance of Document, is it safe to say that document is an instance created from the Document constructor? For example, when I'm using DOM, is this what is happening in under the hood?:

let document = new Document();

where Document() is defined as something like:

class Document {
 constructor()
 //some properties and methods
}

Also, when the following codes are executed:

let link = document.querySelector('a');
link.textContent('This is a link');

is this a case where link inherits prototype from Document and the method textContent is invoked through a setter:

class Document {
 set textContent(x){
  some_variable = x;
 }
}

Is there a way to see the source code of Document other than console.log(Document)?
