I have never never understood the basics of these things like closures, lexical scoping and data structure etc. but this guy deserves hats off.... literally you need a gold medal for teaching in such an awesome way. i am first time commenting on any youtube coding video.
Wow, thanks!

Happy to help🤗☕️
I have not shared your videos links to anyone but I have recommended many friends to watch your videos . if they don't know any topic and try to ask me then I use to say "AAGAR AAP NE CHAI AUR CODE PE HITESH SIR SE PDE HOTE TO MERE SE NHI PUCHTE ", No doubt you are super. keep making videos and get motivated . I started watching your videos 3 years back but i was never serious but now I am int the stream. Once again thank you sir.
apana poura dimage lagaya ha
mein bhe yahhe karuga insh'ALLAH
13:07 you are the best. baki youtubers k video ko dekh kar samjh nahi aya but yeh video dekh kar mere atma ko santushti mil gaya.
Ab Jake Maine aapko subscribe Kiya hai sir . Meri Jo aadat hai pehle dekhta hun uske baad believe karta hun 😅😅. Aapki playlist kafhi achi hai aur mujhe mja aaya aur maine aapne berojgar dosto ko bhej diya hai aur unko motivate bhi kar diya hai aur aapki playlist jarur dekhenge. Thank you so much Sir 🫡🫡
Aaapko hirday se naman hai prabhu......aapse to interview dene wale hi nahi balki interview lene wale ko bhi sikhna chahiye....aapka video to mai dekhta and like share karta rahta hu but ispe to aapne comment likhne ko majbur hi kar dia
yeah definetly sir it is one of the good examples of closures but still we can do the same task with the help of arrow function also
here the code
const orange = document.getElementById("orange");
const green = document.getElementById("green");
orange.onclick = () => clickHandler("orange")
green.onclick = () => clickHandler("green")
function clickHandler (color) {
document.body.style.backgroundColor=`${color}`
}

very very helpful playlist Thank you so much sir for this Premium course on javascript for free..
1.5x me bhi ek hi baar me samajh aa gaya. waah kya chai hai haha. Thank you so much sir..
Sir very nice. aapney bilkul desi method me samjhaya to samajh aa gai otherwise mujhe 7 din ho gaey hen me isee topic par hi phsa hua tha. aksar videos or blogs me bohat mushkil examples di jati hen jo samajh me nai aaten.
This is the best explanation for closures ever, Thanks man
application of this Lexical scope was totally new for me. very intersting
Woww amazing. What a crystal clear explanation.
Thank-you so much sir.
I don't see any video , but just came to learn about closure , and Hitesh sir's teaching is ABSOLUTEBEAUTY, and he teach me how to read documentation that most important thing for me
yes i watched few other videos before this, lekin my concept got cleared when i watched this video. Thanks Hitesh Sir 🙂
Simple Crisp Clear now i know about closure and lexical scoping.Thanks a lot Hitesh SIr
Badhiya aaisa sikhayege to koi bhi sikh jayega coding.
00:03 The video will cover two interesting topics: closure and lexical scoping.
01:47 Understanding closure and its access to outer function scope with MDN docs.
05:36 Lexical scoping does not allow access to variables declared inside a function in the outer scope.
07:55 Inner functions have their own execution context and share memory with the outer function.
11:51 Understanding Outer and Inner Function.
13:37 Explanation of lexical scoping and its significance. Detail explanation of closure through an example
17:32 Lexical scoping and closure return the entire lexical scope of a function when a complete function is returned.
19:14 Using onClick event and changing background color in JavaScript
22:27 Understanding the difference between a function and a reference to a function.
24:03 In Summary Functions have access to variables defined in their outer scope.
Closure allows a function to retain access to variables from its lexical scope
Mini project based lexical scoping and closure example was cheery on the cake!!!!!
Concise and crystal clear.. Awesome, Thanks ❤❤❤
Here I got Cristal cleared the concept of closure
Thank you so much sir 🙏🙏
Your way of teaching is awesome
Kya shamjhaya sir, kya hi intelligence hy bhai, mza agya! Thank you soo much!

one of the best lexical scope and closure video ... maza aaya
FINALLY completed the series. This series of yours gave me confident to more dive into JS environment. I believe if I came across this masterpiece a year ago, It would've been a great investment. Thank you sir💗
The best part of video is

mereko nahi lagta ki ham isko bhulenge
Finally 2nd time completed whole series
Thank You so much @Hitesh sir for such an amazing playlist 😍😍🤩🤩😇😇
The best tutorial on the internet ever!

yes deal done and thankyou for in depth js series lane k liye maza aa gya 90 % plus improvement in my js skill thankyou so much again and again
"Chai aur Code, you've created a masterpiece with your JavaScript tutorials. Thank you for your brilliance!"
The best explanation of closures and lexical scope, thank you sir
Hindi mai sikkh na is a superior way of learning, thank you Sir ji!
Awesome explanation for that last part "lexical scoping" in coloring background!
Revise after 4 month and this time understanding is mindblowing
Lexical scoping completed at time stamp 13:30
Here is something different from other creator who doesn't give proper example of closures they only say closure is created when a function is defined inside another function and allowing inner function to access variable from outer function's scope. AS Well as they give simple example of lexical scope for understanding which is really tough for understanding this topic. But you nailed it guruji 👏
ye only course hi nhi ye to js ka Ramban course h jisne chai or code se padh liya wo to bhul nhi sakta Thanks for hitesh sir chai or code will growth soon
very well explained.
Thanks for such kind of explanation
finally koi yt ki playlist Finish kiya first time in my life
same here yr
25:40 so here's the explanation and my understanding of this particular example ---
The onclick here requires a reference of a function so that it can call it when the click event occurs on corresponding button, we always pass reference in this type of situation to prevent the function to get executed immediately.
But the problem is we can't just pass the reference of the function because as we know it requires the color in the form of parameter and we are noy storing the reference in variable like structure such as let refHolder = clickHandler; so we can't call the refHolder later with the color parameter later in code such as refHolder('blue').
In reality, we are giving the reference to onclick which doesn't have an in built functionality or human intelligence to call this clickHandler with argument based on the button.
So now we actually have a tiny war between onclick() demanding a reference and clickHandler(color) which demands to be called with a parameter only otherwise error.
Now in order to fullfill the demand of bith entities, we can we will indeed call the clickHandler() with color parameter passed ( demand fulfilled ) but at the same time we will do something that a reference is given to onClick function ( which it strictly demands ), we will return reference of an inner function which does the main work or logic( demand fulfilled ) ( Very important thing to note here is this could not have been achieved without the feature of lexical scoping )
Lexical scoping 00:01 to 13:45

Thanks 🙏 SIR ❤

Hindi main aap ka voice bahat hi achha lagta hai.
Lexical scoping ensures that:
1) Functions have access to variables defined in their own scope and in any parent scopes.
2) Variables are not accessible outside the scope they are defined in, preventing unintended interactions and potential bugs.
Sir, hmara safar saathme kaafi acha rha lots of love from my side❤.
M js ki series apni yhi khtm krrha hu plan to thaa aapse pura react,nodejs,and more n more pdhne ka but now m apni ek nyi journey shuru krne jaarha hu i am goint to start from C then C++ taaki core knowledege haasil hoske.
Bye sir❤
Journey kahi b chale, gyaan kahi se b lo, aate jaate milte rhna chai pe. 😁
inshallah😆@@chaiaurcode
My so many myths broken today related to closures, Thank you sir

Thank you sir ❤.. maza aya apke sath smoothly js padh paya 🤌
Thankyou so much sir for this after watch this video my closer concept perfectly clear thanks.🙏👍
13:39 lexical scoping is completed
you are god of javascrript sir!
Lexical scope is everywhere. All functions can access global variables. However variable or properties declared inside a scope is generally not accessible by the parent or global scope. I think the window itself is a function. I found it pretty early, but still, I hesitate to state this. Hitesh Sir if you're reading this comment then please correct me if I'm making any mistake.
thanks sir for this series. today, I completed this series 😊😊
thank you so much sir for this JS series.
lexical scoping from 3:00-14:00
rest from 14:00 -closure
Always good video same as good quality and high energy
best example for interview
sir i liked your speed of teaching, love u sir
Sir mujhe laga closures tuff topic hai ye to bada aasan nikala
