JS Object-oriented

The inheritance of call and apply mode can only inherit the private properties and methods in the constructor, but not the prototype in the constructor, which can only be obtained by the prototype inheritance, so it should be inherited in the way of prototype and constructor.      Each instance inherits all the properties of the constructor, and no instance has a constructor attribute, which points to the constructor attribute in the prototype in the constructor, and looks at the site of Ruan Yi-Feng. When a private property in an instance has the same property name in a prototype, the output property is a private property and the private property has a higher precedence than prototype http://www.cnblogs.com/treasurelife/archive/2008/03/ 05/1092251.html
