(If you have done a website, then you probably have used some JavaScript class libraries. In this case, you may be grateful to these unknown library authors. These authors -- the warriors in the field of web development -- all face the same problem of encapsulation. They will spend a lot of energy on one of the classic object-oriented problems, that is, how to encapsulate their own code so as to separate it from the code of the class library users.
