[@gunam7343]

[@Ghummakad_bhaya]

Bro, my eyes are not closing after watching this 😄.Please keep on posting these deep knowledge 🙏🏼

[@abhisekpradhan9353]

same with me :)

[@anjalii1102]

inheritance in JS => When an object trying to access variables and properties of another object prototype is an Object that get attach to function/method/object and this object has some hidden properties Whenever we create object/ function/ methods/ array/ variable , these all are attached with some hidden properties, which we call prototype __proto__ is reference to prototype ( or it points towards prototype ), if we want to access prototype, we do __proto__ prototype object has a prototype of its own, and so on until an object is reached with null as its prototype, this is called prototype chaining

[@AkashhGuptaa]

Thanks for summarizing buddy

[@porobertdev]

Just wanna point out that the __proto__ is an old method. There's a new method (somewhat inconvenient if you ask me): Object.getPrototypeOf(obj). Learned from TheOdinProject 🙂

[@astroflexx82]

Don't use __proto__ to access an object prototype, use Object.getPrototypeOf() instead.

[@techtube2404]

awesome explanation. First, I used to read on MDN then refer to any video/blogs/articles for a simpler and short explanation. Now firstly I'll watch your video then refer any other study material. Please never stop making such great videos.

[@disenchanted_dove]

Awesome video Akshay! Just a side note that strings,arrays all get coerced​ into its object equivalent called as wrapper object when we try to access the built in properties. This is the reason why we use the dot(.) Operator to access them.

[@prateekgautam7398]

Honestly, Your last mybind example made me understand even more better. That was good. Keep up the good work sir.

[@sohailmohammed4024]

Interviewer asked me same question I explained it beautifully and he was surprised on my explanation and I got selected in interview too Thanks to Akshay brother for giving super content

[@error04354]

Hey can explain and advice what is the major and important interviewers are ask the question. What I do for interview

[@countmein5164]

Idk wtf I was doing 3 yrs ago but here I am. Learning js from gold contents. Thanks for Namaste JavaScript episodes🎉

[@abhijeetyadav1647]

If not the best content out there on prototypal inheritance, it surely bridged the knowledge gap between __proto__ and prototype. Thanks Akshay for the video. keep up the good work. Quick tip: __proto__ is on the object instance, prototype is on the constructor function.

[@adnanahad]

Aap hi ho jo itna deep padhata h aur itne ache se padhata h... Aur sab kuch smj aata h... Practice karne mai b maza aata hai really thankful to you... I love u sir...please make more videos in namaste javascript

[@ashwanikumar183]

I was quite confused by this topic for a long time, you make it simple and great explanation. I would genuinely request you to create the JavaScript Series for all the possible topics.

[@canyouvish]

and now we have Namaste Javascript ♥

[@dhruvthakkar4350]

Extremely well explained. I watched from udemy paid course but couldn't understand. but this person explained me perfectly.

[@rishikeshsanjekar1349]

I've watched many JS tutorial on KZbin but your explanation is totally different You are JavaScript King 👑

[@abs542]

Very helpful. Easily understood otherwise a highly confusing topic. Keep up the good work.

[@mohanrawat5052]

[@somewhere_in_bharat]

Subscribed. Finally found someone who is teaching in a way I want to be taught or I teach someone. Thanks, dude!!

[@NuhAleph]

I found my javascript tutor. Thank you, god bless you.

[@raviaryan6723]

first time i watched your video and understand what really is a prototype. Thanks for the wonderful explanation in the coding way.

[@tauseefanwardo]

I was lost and here you are man! Lovely, marvelous, mind boggling, seriously man, you make javascript fun to learn.

[@AbhishekSharma-cq2hw]

Thanks for making this extremely helpful video!! Even though this somewhat a confusing topic for me, I do have a much better understanding of prototypal inheritance after watching this video :)

[@milosleng1175]

good videos bro. I have watched tons of Videos on YT on the topics you presented, but sometimes things do not click on the first time, etc, so I keep coming back to the concepts that cause me issues. I love simplicity of your channel, you really helped me clear some things up! cheers!

[@rohitkudalkar92]

i feel lucky to found your channel. Love ❤️ and Support.

[@aparnaiyer5873]

WONDERFULLY EXPLAINED ! IT IS RIGHTLY SAID THAT IF YOU CAN NOT EXPLAIN IT SIMPLY ENOUGH THEN YOU DO NOT UNDERSTAND IT... THANK YOU VERY MUCH !

[@bhaveshmaisuria544]

Really Deep dive coching. First time clearing concepts...Rocking.

[@amitsingh-rb6jl]

Much better explanations than all the videos I have watched till now on this topic, liked the video as soon as I got what you were explaining. Now subscribing to your channel for the depth of knowledge you are trying to provide thanks a lot it helped a lot.

[@vikas.gaurav]

I read it many times from MDN but never understood it completely, now it is done😍

[@arghyaghosh2515]

Same bro🤣🤣🤣

[@BittuKumar_Web]

what has to do in place of, object.__proto__= object2. he suggested not to do like this. what has to do in place of this.

[@aashishomre1624]

use Object.create(object2)

[@alpaytripleplay5150]

finally an explanation that does not use animal/user constructor functions for examples. using arrays/objects for examples finally helped this topic click better for me

[@rajapavithraselvaraj5937]

Hi, Your videos and explanation are awesome. If you could mention timestamp to the topics in video's description it would be great. Keep Spreading the Knowledge

[@jeet_aj77]

2,3 jagah videos dekhi samajh nahi aaya bilkul bhi...yha akdam mast samajah aaya. Thank you bro❤

[@dipinkrishnan]

Usual prototype expiation begin with car colour seat etc 🤦🏻‍♂️ and I forget every time ... Most simplest way to explain prototype and js inheritance. Love the way you detail things ..

[@XYZ-bz8tf]

Yesterday I wasted my 3-4 hours on this topic with some videos on KZbin. However, I did not fully understand the subject, there was always a missing piece. I could implement but this was just usage without understanding fully. Now, in 20 minutes, the subject has become completely clear in my head without any doubt. There is a serious amount of information pollution on the Internet. You really did a great job Akshay. I will be watching all your javascript-related videos for the next 2-3 days. Thank you so much for good and precise information.

[@gururajchadaga]

This channel's content gives me so much confidence. Thank you so much.

[@adityaagrawal4466]

you know what's more beautiful than functions in javascript, it's your teaching style ❤

[@ameyzulkanthiwar9148]

Thank you for explaining in a practical way. It is very helpful.

[@vishwasrvishu9267]

The most important thing I like in your videos …. You always have that confidence on :-)

[@vinitrai5020]

Hey Akshay, wonderful lesson. Thanks a lot for making it so simple.Your videos make JS easy and hence more interesting,as they say ''once you understand you get interested" .I would appreciate if you could come up with a video on DOM Manipulation without using Jquery. I know there are many resources available for this on the web but a video from your end will definitely clear the things in a much much better way.Hope to get a solid foundation video on DOM maipulation with Vanilla Javascript. Thanks in advance. :)

[@akshaymarch7]

Thanks for your suggestion, Vinit. That was not in my list, but even I think that would be helpful for a lot of people. Will surely try to cover that in upcoming videos. :)

[@pranshu_g]

Can't believe I finally understand this dunderproto thing 💯🔥.. I actually liked your video in between & then continued watching.

[@akshaymarch7]

Do watch Namaste Javascript web series on the channel, you'll love it brother. ❤️
