Javascript new the essence of an object

In the past, these things were clearly understood, but they could not be explained, nor did they go into depth. Today, when I read "enlightened JavaScript", I saw the author's description, and the "toilet" was opened.

The excerpt is as follows. The author makes it clear:


The process of creating an object in the form of var anObject = new aFunction () can be divided into three steps:

The first step is to create a new object;
Step 2: Set the built-in prototype object of the object to the prototype object referenced by the constructor prototype;
The third step is to use this object as the this parameter to call the constructor and complete initialization such as member settings.
