javascript - Prototype inheritance is not working as expected -

I have read my javascript since childhood and after that I should override the manufacturer in case of prototype heritage. But I am surprised to see that the following example gives the same output to the console, even if the override controller statement is commented on. Please enlighten.

  function A () {console.info ("A Creator"); } Function B () {console.info ("b constructor"); } B. Prototype = estrototype; B.prototype.constructor = B; // Do we really need this statement? Console.info ("CP1"); Var B = new B (); Console.info ("CP2"); Before participating the Constructor, there is a problem in your code. You   Prototype  and  are doing both by applying aprototype , 
 
  bipartotype = aprototype;  
 
 This means that you can not effectively identify the parents of objects created by these functions. Try it 
 
  console.log (New B) Example A, New B (Example B); // True Truth  
 
 This is expected, because  B  is created by  B  and  B  Is made from  a  prototype but 
 
  console.log (new A () example a, new A () example b); // True Truth  
 
 Whaat? An example of  a  is an example of how  b  is? Because since you have  b. As prototype  is made, in the form of a  as a prototype , when an object  A  is its prototype ( aprototype   A < The prototype of the object created with / code> is that the prototype of  B  exists anywhere in the series, because  B.prototype  is the same as  aprototype , < Code> A  to  B . . 
 The correct way to do this is, 
 
  B. Prototype = object. (Aprototype );  
 
 Now, you are creating a
