Adding a prototype to an object literal

Question

I have some object, say son, which I\'d like to inherit from another object father.

Of course I can make a constructor function for father,

Answer 1

That's incorrect jmar777. If for example you have

var X = function() {};
X.prototype = {
  protoFunc1: function() { console.log('p1');},
  protoFunc2: function() { console.log('p2');}
};

X.protoFunc1(); // is not a function 

That means that what you're doing:

X.prototype = {}

is just creating an object called prototype. Not the actual prototype. To use prototype you have to use constructor functions.

if however you modify it to this (constructor method)

function X(){};
X.prototype.protoFunc1 = function() { 
    console.log('p1');
}
X.prototype.protoFunc2 = function() { 
    console.log('p2');
}

var x = new X();
x.protoFunc1(); //'p1'

It would work.

Either go the object literal method without using prototype or use the contructor method using prototype.
