Definition and Usage The prototype property allows you to add properties and methods to an object. Syntax object.prototype.name=value Example In this example we will show how to use the prototype property to add a property to an object: function employee(name,jobtitle,born) { this.name=name; this.jobtitle=jobtitle; this.born=born; } var fred=new employee("Fred Flintstone","Caveman",1970); employee.prototype.salary=null; fred.salary=20000; document.write(fred.salary); The output of the code above will be: 20000 Reference : http://www.w3schools.com/jsref/jsref_prototype_math.asp For more details see : http://www.w3schools.com/js/js_object_prototypes.asp http://javascriptissexy.com/javascript-prototype-in-plain-detailed-language/

All JavaScript objects inherit the properties and methods from their prototype. Objects created using an object literal, or with new Object(), inherit from a prototype called Object.prototype. Objects created with new Date() inherit the Date.prototype. The Object.prototype is on the top of the prototype chain. All JavaScript objects (Date, Array, RegExp, Function, ....) inherit from the Object.prototype. one simple Example about the javascript Prototype. function person(first, last, age, eye) { this.firstName = first; this.lastName = last; this.age = age; this.eyeColor = eye; } var myFather = new person("John", "Doe", 50, "blue"); var myMother = new person("Sally", "Rally", 48, "green"); document.getElementById("demo").innerHTML = "My father is " + myFather.age + ". My mother is " + myMother.age; output: My Father is 50. My mother is 48. Referenced by : www.w3schools.com/js/js_object_prototypes.asp
