Summary of several ways to inherit JS object

Today I learned a bit of JS inheritance, JS in the inheritance of the main four kinds, prototype inheritance, constructor inheritance, call/apply inheritance and es6 inheritance of extend.
1. Prototype Inheritance:
Prototype inheritance mainly uses the prototype of the JS object to refer to the parent class's constructor to copy the parent class's methods.

//define a person class     functionPerson (name) { This. name=name; }      //Greetingperson.prototype.sayhello=function() {alert ("Hello,my name is" + This. Name); }           //defining the Man class, inheriting the person class    functionMan (name,age) { This. name=name;  This. age=Age ; } Man.prototype=NewPerson (); varman=NewMan ("The Old King next Door", 30); Man.sayhello ();

2. Constructor inheritance
The constructor of the parent class is called in the subclass to complete the inheritance.

 //define a person class     functionPerson (name) { This. name=name;  This. sayhello=function() {alert ("Hello,my name is" + This. Name); }      }       //defining the Man class, inheriting the person class    functionMan (name,age) { This. constructor=Person ;  This. Constructor (name);  This. age=Age ; }    varman=NewMan ("The Old King next Door", 30); Man.sayhello ();

3.call/apply inheritance
Using the Call/apply method to invoke the parent class constructor to implement inheritance

 //define a person class     functionPerson (name) { This. name=name;  This. sayhello=function() {alert ("Hello,my name is" + This. Name); }      }       //defining the Man class, inheriting the person class    functionMan (name,age) {Person.call ( This, name);  This. age=Age ; }    varman=NewMan ("The Old King next Door", 30); Man.sayhello ();

4.extends inheritance
Use ES6 to define the method of the class, similar to the way Java defines the class to implement inheritance, note that some browsers are incompatible--

' Use strict '; //define a person classclass person{//constructor FunctionConstructor (name) { This. name=name; } SayHello () {alert ("My name is" + This. Name); }} class Man extends person{constructor (name,age) {//calling the parent class constructorsuper (name);  This. age=Age ; }            }    varman=NewMan ("The Old King next Door", 30); Man.sayhello ();
