In 《JavascriptPlay-and-play inheritance(I)", I mainly introduced object disguise to implement inheritance. Here we will first discuss the advantages and disadvantages of this method.
Undoubtedly, this method is easy to understand and calls the constructor of the parent class in the subclass. In addition, the biggest advantage of this method is that constructor inheritance can implement multiple inheritance. Review thisCode:

VMware is a "Virtual PC" software that allows you to run two or more windows, DOS, and Linux systems on a single machine. VMware uses a completely different concept than the multiple boot system.
