Objects and Prototypes In-depth 18 - Inheritance In JavaScript

Let's put together all the various prototype concepts we've learned so far to build a multi-level hierarchy of objects.

Just amazing! I would really request you to write a text book on what ever you teach. The way you explain is really logical. Best teacher ever. Can't just thank you enough!

I am glad you brought this to us. It was very unclear and complicated as well, when i started. Now that i have watched this video tutorial, i feel confident. Hope it covered everything i wanted to know about Objects and Prototypes. Thank you so much for your time to create this video. You are genius indeed.

Additionally, this is from the Mozilla Developer Network site:
Warning: While Object.prototype.__proto__ is supported today in most browsers, its existence and exact behavior
has only been standardized in the ECMAScript 2015 specification as a legacy feature to ensure compatibility for web browsers. For better support, it is recommended that only Object.getPrototypeOf() be used instead.

This is a Great Great example. Thanks so much for this playlist!!

The best video's on Prototypes. I can finally say i understand it now.

Your tutorial in the prototype is the best. Thank you!

Finally, after doing some more research it looks like the following is a recommended way of doing inheritance in Javascript (although using 'class' in ECMAScript 6 may be even better):

function Animal(name)
{
this.name = name
}

Animal.prototype.makeNoise = function()
{
console.log("Generic noise")
}


function Dog(name)
{
Animal.call(this, name) // call parent constructor
}
Dog.prototype = // Dog prototype is create with Animal's prototype as its parent

Dog.prototype.makeNoise = function()
{
console.log("woof")
}

You are genius... Great tutorial Koushik... thank you...

I thank you from the bottom of my heart. Your tutorials are outstanding. You explain the complex topics in a simple way. I always wonder how it would be possible for me to describe any subject in the similar way. Can you come up with a video tutorial on how to understand and explain the concepts to others in an easy way :) Thanks again!

[smartguyk]

Thank you so much. You explain so well, taking step by step approach. I am sure programmers coming from C++ and Java like background have a better view of Objects and inheritance in JS.

[jsvihla]

the way you explain it makes it look so simple :)

[hermannkumbong]

This guy made this look so easy. thanks alot

[himanshumewari]

one of the best videos on javascript . could you please make some videos on angular 4

[venkatasrikanthp]

Great Tutorial Koushik, Really very nice explanation...:)

[webprogramming]

excellent lessons recommend you very pls more lessons about regards big thanks for once more :)

[Arganoid]

In practice I assume you would not write mgr.__proto__.__proto__ = Employee.prototype, you would write Manager.prototype.__proto__ = Employee.prototype

Great tutorial for Object Oriented Programming Thanks a Lot :)
