Beej's Bit Bucket2 months agohttp://beej.us/blog/data/javascript-prototypes-inheritance/在JavaScript中，原型继承与基于类的继承不同：对象的原型是对其构造函数原型属性的隐式引用。如果在对象上找不到某个属性，则会沿着该对象的原型链向上查找，直到找到该属性或到达原型链的末端。通过将一个构造函数的原型设置为另一个构造函数的实例，可以形成一条链来实现继承；之后修复构造函数属性以保持正确的引用非常重要。
Beej's Bit Bucket2 months agohttp://beej.us/blog/data/object-oriented-programming-2/Inheritance allows a class to inherit attributes and methods from a parent class, forming a class hierarchy.The superclass (base class) provides common functionality, and subclasses extend it, improving code reuse and maintainability.Polymorphism enables subclasses to override methods, and the correct method is called even when using a base class reference.Example: Animal superclass with legCount and hasFeathers; Armadillo subclass overrides eat() and adds armorRating.In Java, all methods are virtual (can be overridden) unless declared final; in C++, methods must be declared virtual.
