I've read countless JavaScript blogs and books on Constructors and Prototypes but they don't explain it as crystal clear as you do. You should seriously write a book man. Would love to see you break down and pick apart an angular or node.js tutorial. Thanks for making these videos. I know making them takes ALOT of work and time to develop.

Your channel is like a big book of secrets, contains every thing a programmer needs to know about a programming language, Thank you fo that :)

I'm only 35 minutes but you've already solidified a few concepts that have been somewhat unclear to me for the last few months. My sincere gratitude! Thanks!

[jeannemccabe]

Adding the time stamps is a wonderful idea. When I am not just trying to learn from you tube videos, but trying to do a real program, I can never remember a useful video. This will make finding your examples so much easier. Thanks for going the extra mile.

The most concise and clear tutorial in JS OOP I've ever watched. One request is a link to a project where I can practice on. Maybe a CRUD project like Customer Management or something else?

[DarkPsy]

This is freakin' legendary! The best part I like about your style is how you are so quick in going over concepts, which all the other tutors take ages to go through at the ultimate cost of the student completely giving up on the tutorial! Great job sir!

[kal-el-shadowfax]

This video explains OOPs concepts in JS perfectly and to the point, instead of going in circles when reading any book! Thanks much!

I believe this may clear some confusion. At around 32:44 Derek says that when the prototype is changed (from the base Object (which is default )), that the prototype.constructor will point to the Object object... In reality it points to the function the prototype Object was set with:


function Animal(){
this.kind="Animal"
this.breathing="yes"
}//default prototype =object Object

function Cat(){
this.type="Cat"
this.sound="meeow"
}
Cat.prototype=new Animal(); //set new prototype ...mess up .constructor
/// needs Cat.prototype.constructor=Cat be accurate
var kitty1=new Cat();



Logs:
function Animal(){
this.kind="Animal"
this.breathing="yes"

I am not able to handle more than 2 languages at one point of time, how is is possible to give such an awesome explanation on almost all programming languages out there. Am awestruck! You are a superman!

[ParrhesiaJoe]

This is a superior video to those I've watched recently. I'm coming from C#/C++ with very little javascript, and I was looking for a good primer. You are:
#1 Easy to understand. Good communicator. Clear audio.
#2 Concise and quick with your accompanying code.
#3 Smart about the educational route you go down.

I think this is too dense for a beginning programmer to learn from in one go, and my only advice to them would be... watch it four times. It is hard to find information of this quality and density presented by someone without an Indian accent... (I'm only half joking)

[StingJia]

For get and set, I think you should name both getAddress and setAddress just to address. It makes more sense.

[boolmax]

I didn't understand OO JS before this video. Thanks!

[stevenlane]

The 'PERFECT' technologist and 'MASTER' instructor!!

[jesusmiguel]

It would be very cool if you start doing tutorials with projects. Like learning JavaScript by doing a dynamic site, learning HTML by doing a static site, etc. Great tutorials by the way.

[LouSaydus]

in the first 3 minutes i learned more than I did taking about 2 weeks of online courses and speaking to javascript developers. People really need to learn how to communicate better.

[RatchetSK]

BY FAR the best books for javascript are the 'You don't know JS' series. definitely check them out

[saharFTW]

at 38:08 - the extend function -
why not simply do
Child.prototype = new Parent();

Child.prototype.constructor = Child;

[bjblastyoass]

The work you do is really amazing, and you should be miles more popular than you are. I'm a recent graduate with an AS in Software Development, and I certainly learn more from your videos than I learned in *most* of my college classes. I really appreciate it man. Thanks for everything.

[robkremers]

Thanks Derek for this and for the tutorial 'Learn JavaScript in one video'. I have chewed on the book 'JavaScript The Definitive Guide'. So I had some knowledge regarding JavaScript but these two videos are given an awesome overview, connects everything and every bit of JavaScript comes to life. Amazingly good stuff!
