JS class method, object method, prototype method

1, the object method: Includes the method in the constructor function and the constructor function prototype above method;
2, class method: In fact, the class here is a function. In JS because the function is also an object, so you can add properties and methods for the function, this method in node with more;
3, the prototype method: commonly used for object instance sharing, in the prototype above to add the method, you can realize the sharing. This makes it necessary to allocate the appropriate memory for each instance when it is initialized.
When a function in JavaScript is a constructor, it is a class that, with the new operator, can return an object.

function people (name) {      this.name=name;      Object method This      . Introduce=function () {          alert ("My name is" +this.name);      }  }  Class method  People.run=function () {      alert ("I can Run");  }  Prototype method  People.prototype.introducechinese=function () {      alert ("My name is" +this.name);  }    Test  var p1=new people ("windking");  P1. Introduce ();        The object method needs to invoke People.run () by instantiating the object  ;          The class method does not need to invoke P1 by instantiating the object  . Introducechinese (); The prototype method also needs to be invoked by instantiating the object
