Inherting from Prototype in Js

prototypeInheritance.js

/*
	This gist covers creating a subclass from a baseclas, overriding in the prototype chain, and adding properties 
  to the master Object prototype
*/

// baseclass
var Job = function() {
  this.pays = true;
};

// add print method to the Job prototype
Job.prototype.print = function() {
  console.log(this.pays ? 'Good' : 'Bad');
};

// creating a subclass object TechJob from the baseclass Job
var TechJob = function(title, pays) {
/*
	Calls the constructor of Job and makes it the parent of TechJob class.
  But, we haven't inherited the print method yet from Job!
*/
  Job.call(this); 
  this.title = title;
  this.pays = pays;
};

// Inheriting method from the prototype of parent class
TechJob.prototype = Object.create(Job.prototype);

/*
	Set the constructor of TechJob to the TechJob we created above(Because this has the call to Job constructor)
*/
TechJob.prototype.constructor = TechJob; // 

// Overriding the print method in our subclass

TechJob.prototype.print = function(){

	console.log(this.pays?this.title+' is a Nice TechJob':this.title+' is a Bad TechJob');
};

var softwareDeveloper = new TechJob('JsDev', true);
var phpDeveloper = new TechJob('phpDev',false);
console.log(softwareDeveloper.print());
console.log(phpDeveloper.print());

// To add a method to main parent Object class
Object.prototype.printToConsole = function(){
	console.log("This is from the master!");
};

console.log(softwareDeveloper.printToConsole()); // From the master!
