Inheritance enables you to define aclassthat takes all the functionality from a parent class and allows you to add more. Using class inheritance, a class can inherit all the methods and properties of another class. Inheritance is a useful feature that allows code reusability. To use class inher...
Class Inheritance To create a class inheritance, use theextendskeyword. A class created with a class inheritance inherits all the methods from another class: Example Create a class named "Model" which will inherit the methods from the "Car" class: ...
封装(Encapsulation):将数据和操作数据的方法封装在一个对象中,使其成为一个独立的实体,外部无法直接访问对象的内部实现细节。 继承(Inheritance):通过定义一个基类(父类),其他类可以继承该基类的属性和方法,并可以在此基础上进行扩展或覆盖。 多态(Polymorphism):不同对象可以对相同的方法做出不同的响应,即同一个方...
本章移到“Object oriented programming”和"classes"。 看‘class orientation‘ 的设计模式: instantiation, inheritance, relative 多态性。 会重点讲解oop理论,当讲到Mixins, 我们会最终联系这些思想到真实的JS代码。 在这之前会先说大量的概念,pseudo-code,所以不要迷失,stick with it!! Class Theory OO or cl...

for âmultiple inheritance.â Many see this is a good thing, because the complexity savings more than make up for the âreducedâ functionality. But this doesnât stop developers from trying to fake it in various ways, as weâll see ...
