Obtain the prototype function

I'm facing an issue with my code:

function Param(){
  this.name = 'sasha'
  this.method = function(){
    return this.name + 'native method'
  }
  this.pro= function(){
 debugger
  // Param.prototype.method() //undefined proto method bad!!
 //  this.__proto__.method() //undefinedproto method 
 Object.getPrototypeOf(this).method()  //undefinedproto method 
  }
}
Param.prototype.method = function(){
    console.log(this.name + 'proto method')
  }
 var param= new Param; 
 param.pro()

Can someone help me access the method prototype when this.name = 'sasha'? I found a solution using

Object.getPrototypeOf(this).method.call(this);
.

Is there any other approach to achieve the same result?

Answer №1

A straightforward fix: executeMethod(). This concept is known as method overloading.

If you want to ensure that a method from the prototype is used, you must obtain it explicitly (using any of the 3 methods illustrated), and then specifically call it on the current instance using .call(this). This procedure is perfectly acceptable.

To create a custom pro method that mirrors the functionality of .prototype.method, you can directly assign it like so:

this.pro = Param.prototype.method();

After this assignment, calling param.pro() will execute the prototype method on the named instance.
