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.

@derekbanas 9 лет назад

+P8860 Thank you :) it is nice to hear that I cleared everything up. Maybe I'll make a book some day and sell it for $1 just to see how many sell. Angular and Node are coming right after JQuery.

@jeannemccabe5752 7 лет назад

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?

@ParrhesiaJoe 8 лет назад

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)

@derekbanas 8 лет назад

Thank you for the very nice compliments :) I greatly appreciate them.

@DarkPsy4 7 лет назад

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!

@robkremers 8 лет назад

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!

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!

@derekbanas 8 лет назад

+Sandeep Devaraj Thank you for the compliment :) I guess I have just been switching back and forth for so long it is natural. I definitely prefer some languages over others though

@velocitynetworking2439 5 лет назад

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 ......to be accurate var kitty1=new Cat(); console.log(kitty1.constructor) ///// Logs: function Animal(){ this.kind="Animal" this.breathing="yes" }------incorrect

@StingJia 8 лет назад

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

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.

@derekbanas 9 лет назад

+Jesus-Pierre-Miguel Salgado III Thank you :) I think I kind of did that in the past and those videos still hold up. I made sliders, tons of website layouts, shopping carts, etc. They are kind of hard to find in my sea of 700 videos, but I'll point you towards them if you'd like to see something specific.

@saharFTW 8 лет назад

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

@erichuang6339 8 лет назад

Exactly. Using his function can't get the toString() to work.

@dynamic21 8 лет назад

@Derek Banas - I'm also interested in the answer to @SaharS question. And thank you for such a straight forward and in-depth explanation of OO JS, this was very helpful.

@chesminsky 8 лет назад

+1, that confuses me too. everything works without Temp

@fabdlnltc 8 лет назад

I think he made that (the extend function), only because he wanted to evade duplicated code in every type of animal he thinks. And i think, doing: Child.prototype = Object.create(Parent.prototype); Would make more sense... And lastly, about *Child.prototype = new Parent()* If you do that, you inherit *ALL the Parent Object*, not only the _Parent Prototype Object_.... That means, all the things defined inside that _Parent Object_ would be public too. For example; if you have: function Parent() { this.somethingAboutParents = "Yells all night"; } Using your aproach, Child.prototype = new Parent(); For each Child you create, you will have access to that property new Child().somethingAboutParents // --> 'Yells all night' Using *Object.create(Parent.prototype)* instead, you only inherit the *Parent Prototype Object*, not *all* the *Parent Object* including his _Parent Prototype Object_.

@MrYourFilm 8 лет назад

I have no idea if you have actually done this ( not taking the videos posted onto your website in account ), but you should create videos that build onto these main videos, in a way of using the newly obtained knowledge to create something, a seperate, simple project. This would completely solidify everything learned in this video. It is possible to go out and brew up personal projects, but it'd be a fun thing to watch/follow, and you'd be attracting a greater audience ;) Thank you for the video as it is, I've learned quite some things from it!

Love your "Learn... In One Video" videos!! So useful! Have you thought about doing one for Pascal?

@phkonings 8 лет назад

Many thanks for this great overview of the many possibilities. It leaves a bit overwhelmed giving a old school pascal background but knowing OO Design (not programming). I agree it would make sense to elaborate the programming choices and solution path visually with the why 's of the to be solved real live scenario 's providing the starting context. I realize that for example a pizza shop it would mean a video itself. Again, thx. for this great video to get a clue about the 'insane' number of possibilities .

@derekbanas 8 лет назад

+phkonings You're very welcome :) I agree that I could do many tutorials on this topic and I may just do that.

@phkonings 8 лет назад

+Derek Banas ...in the meantime I have had a first look at the patterns book (flanagan) etc. I am really jumping in this exploring it from middle-out. I am currently thinking about the best way to approach a traffic light simulation as a simple state machine (red, green, orange, stop, run, onservice). DesignIdea is 3 objects (timer, trafficlight, display) . My thinking problem is that I see the object-abstraction as objects sending messages to each other and reacting on it based upon object state changes (in a networked object model). Instead of sending messages to each other and reacting on that, I guess they need to invoke each other methods instead. That implies the sending object needs to know the internal behavior of the receiving object instead of sending just a message (event). That 's where I get lost between design and programming.🤔

At 48.58 var derekHero = Hero("Derek"), shouldn't there be a new here? This is a special case too since it is a Singleton. So what is the actual difference between having "new" and not having "new" before constructor function invocation in non-Singleton context?

@xviewmytubex 6 лет назад

Is my understanding that, prototypes are basically a shorthand version of adding properties/function objects to an object, correct? Also, is my understanding that, object creation basically consists of three parts: 1. defining (creating) the object, 2. adding properties (members), 3. adding methods (functionality) to the object and it's properties, correct? I like your tutorials. I'm a total noob. Thank you. =).

You didn't even use getPrice() to get the price of the pizza (54:30) or am I too dumb to understand it?

I don't really understand why we need to reset the constructor in the inheritance section. Exp: Rat.prototype.constructor = Rat

Awesome video! So once I learned OOP and Javascript, what's next? Do I learn Backbone? Angular? I just want to put this in real world usage.

@derekbanas 9 лет назад

+danh27 The normal next steps are things like JQuery, Node and Angular. I'll cover all of those next.

Hi Derek, Thanks for the great video. @38.12 why cant we have this Child.prototype = Parent.prototype; Why did we do this var Tmp = function() {} Tmp.prototype = Parent.prototype; Child.prototype = new Tmp();

Hey Mr. Banas, Great & Thorough Videos. Do you have any videos focusing on the algorithmic method of solving problems to become a better programmer? Solving problems with arrays, classes, recursion & how-to think through complex problems and breaking down to solvable programming blocks of code to go through?

@derekbanas 8 лет назад

+William Quan Thank you :) I have tutorials on object oriented design that should help with that.

Hey Derek, I have couple of questions? How do you create enum in JavaScript? And how would you use it in your Pizza example? Instead of creating a ExtraCheese function, is there a way to create a function named Extra() that has either cheese or veg or meat variables, And based on what user pass, the price is changed. Sorry..if question is not clear..

Whats the point of using a getter or setter when you can just create a method within the object that does both?

at 34:25 you said Wolf instance of Animal, which confused me. Later I understood arcticWolf is actually an instance of Animal, not Wolf. So, can I say a constructor function can not be an instance of another constructor function?
