Object-Oriented Programming-Overview, definition of base classes and derived classes Introduction: Object-Oriented programming is based on three basic concepts: data abstraction, inheritance, and dynamic binding. In C ++,Data abstraction using classesTo inherit from one class:The derived class inherits the members of the base class.. Dynamic binding enables the

or a Feature List page page! This can be expanded on its own; we are here to implement our own feature items by creating an init initialization method, and can pass the parameters you need for this feature page. Functions: (1), Inherit Baselayer, so that the function of the base class can be controlled and used, (2), through the Init initialization method, pass the required parameters, and implement this custom layer needs to implement the function;

Fn[member] = Extend (true, {}, Base.prototype[member], Proto[member]); Else { = proto[member]; } }The constructor property always points to the constructor that creates the current object. Here the constructor of the prototype object is also set to the subclass function. Ensure that you can work correctly when checking the type, you can see the instructions here: Javascript:constructor PropertyFn.constructor = subclass;Makes subclasses also have an i
