Factory mode, that is, a function to encapsulate the details of creating an object with a specific interface.
The function Createperson () can create a person object that contains the necessary information by accepting parameters.
You can call this function multiple times, returning an object that contains two properties and a method at a time.
However, it is not possible to know the type of an object, that is, the object type cannot be determined by Typeof,constructor.
In addition, p1 and P2 have a sleep () method, but they are not the same function instance, it is not necessary to create two identical function instances,
The subsequent creation of object patterns will resolve these issues.

If there is any mistake, please correct me, thank you ...
