Simple implementation of object-oriented programming using Javascript to inherit from the instance code _ javascript skills

This article mainly introduces Javascript simple implementation of object-oriented programming inheritance instance code, and briefly analyzes the characteristics of object-oriented programming and the specific implementation skills of inheritance, which has some reference value, for more information about how to use Javascript to implement object-oriented programming, see the following section. We will share this with you for your reference. The details are as follows:

Object-oriented languages must have four basic features:

1. encapsulation capability (that is, to allow variables or functions of the basic data type to be put into a class to form members or methods of the class)
2. aggregation capability (that is, to allow classes to be included in the class, which can cope with complicated design)
3. support inheritance (parent classes can be derived from child classes, and child classes have parent attributes or methods)
4. supports polymorphism (the same method name is allowed. there are independent processing methods based on the method signature [that is, the function parameter)

These four basic attributes can be supported by javascript, so javascript is indeed a weak type of object-oriented language. Here we provide a simple code for class inheritance.
