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 🫡🫡
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
Hitesh ji In this lecture you have explained this two topics very easily. The topics which sounds very difficult, you made it look very simple with awesome example. Thanks a lot
Thank you so much sir Javascript ki Sabse best series provide krne ke liye Maine puri series follow Kiya jisse mujhe javascript samjh aane laga aur ab kudh se project bhi bana leta hoon.... Again Thank you so much sir 🙏
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}` }
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.
I have watched many channel for javascript but the way you explain all the concepts...i have really became fan of ur teaching style... Hat's off to you 🙌🙏 @chaiaurcode
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💗
Amazing sir . i have watching many videos about lexical scoping and closure but I can't understand but sir after watching yours videos now I realize that its very easy
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 👏
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 )
Super Sir, 4 mobiles in my home so i have subscribed 4 times also i have subscribed office mail id too❤ thank you soooo much sir , i have not shared your videos links to any one but i told to lots of pepole that if you want to learn javascript then you watch the video of chai or code channel
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
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.
Sir abb to jitni bhi videos aa rahi hai sabb deshi ghee mil raha hai. 😂 saara maal abb last mai mil raha hai JS ka.prr abb chai aur code pe subscriber bhi toofaan ke saath chal rahe hain aage dhamaal machega esi playlist pe.Thank you @Hitesh Sir regularity ke liye.❤

Maine puri series follow Kiya jisse mujhe javascript samjh aane laga aur ab kudh se project bhi bana leta hoon....
Again Thank you so much sir 🙏
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.
This is the best explanation for closures ever, Thanks man
Simple Crisp Clear now i know about closure and lexical scoping.Thanks a lot Hitesh SIr
application of this Lexical scope was totally new for me. very intersting
yes i watched few other videos before this, lekin my concept got cleared when i watched this video. Thanks Hitesh Sir 🙂
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}`
}
best teacher ever seen in my coding phase escpecially in mern stack
Here I got Cristal cleared the concept of closure
Thank you so much sir 🙏🙏
Your way of teaching is awesome
finally i understood the lexical scope thank you sir for being here to teach us. love from nepal
Mini project based lexical scoping and closure example was cheery on the cake!!!!!
Badhiya aaisa sikhayege to koi bhi sikh jayega coding.
Woww amazing. What a crystal clear explanation.
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.

Revise after 4 month and this time understanding is mindblowing
Ek baar mein samak aagaya. Thnx Hitesh sir.
one of the best lexical scope and closure video ... maza aaya

Hindi mai sikkh na is a superior way of learning, thank you Sir ji!
koi bhi problem ho solution is always our ❤ hitesh sir
sir apke samjaneme ek calmness hai
I am revising and literally no one explained like you ❤
Awesome explanation for that last part "lexical scoping" in coloring background!
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 )
