[@amirrahman853]

20:45 answer is wrong by the interviewer . arr is been used before created that's a syntax error but the interviewer is answering the question as if arr is defined first and then iterated
for(i in arr){
console.log(i)
}
for(i of arr) {
console.log(i)
}
const arr = [3,4,5,6]
arr.foo = "hi"

[@talkwithpramod9284]

I don't know why but i think she has a notes in JavaScript. 😀😀😀

[@lokeshbhardwaj8774]

20:31 in your code the arr is constant so the for loop will gives the error of undefined, so if you use the arr on top, then you will get this answer from the first loop: 0,1,2,3
And from the second loop you will get this:
3,4,5,6
I don't think so that foo do something, please correct if I am wrong..!!!

[@the-owls-owlet]

Seems like a student of Akshay Saini. Amazing answer girl 🙂

[@hello-world556]

Exactly the way i was thinking.she is prepared like a regular student of saini🙂😅

[@akeditz4428]

I think she is reading it from notes 😂

[@Akramali-gv8me]

Yeah absolutely completed each video of akshay Saini 😀

[@shubhamjani5716]

@@akeditz4428 I thought the same

[@eggrat3381]

bro thats what i thought

[@spiritualcontent763]

That output question of for of and in will throw error as arr is used before it's initialisation.
Awesome interview 🎉

[@DevAditya]

Thanks

[@harshads530]

For each explanation he was saying that's fine.. I would say brilliant..🙃

[@_saurav_jha]

I was watching the video for preparation of my mock interview and simultaneously I asked the same question from Chat-Gpt , you guys wouldn't believe the response given by this lady is exact similar to chat-gpt word by word.

[@Dr.dhumketuIITDholakpur]

agree

[@saumyaranjan1403]

Fun fact: The lady is ChatGPT itself, but with an Indian accent! 😂

[@karansawant5121]

Arrow vs regular function in context to this keyword.
She says the opposite
12:42

[@tirthsuthar6818]

I am learning HTML,CSS by this video

[@jaideepsingh8657]

she is reading from the script. all the questions and answers were given to her in advance. but as it was a mock interview no issues there.

[@sahil-ld1bu]

Akshay Saini rocks everywhere in every JavaScript interview . i think she is student of Namste javascript

[@Lohitpant]

the candidate is giving good answers. Very Helpful video.

[@aditimarathe]

Such a adorable interview as I have ever listened

[@tm---]

[@prathmeshlavate4216]

In the last javascript program the output cannot access arr before initialization

[@AbidKhan-q7v]

in the question of for in & for of it will give reference error: arr is not defined

[@pitambarjadhav9984]

data can be sent from child to parent if you pass a function to a child component and then pass the data as argument from child you will recieve the data in parent component function

[@avanishexplorer]

explained answer in very good way

[@tutormaths3637]

21:33 the answer was wrong and the answer will be can't access arr before its initialization

[@nitishsharma4838]

Initialization cannot be hoist only declaration part can be hoist

[@Proudly_indiann]

[@notappi3982]

isnt the question at 21:04 will through all error coz of hoisting ? i can be wrong do correct me

[@LinhNguyen-gx5fb]

you are not wrong. because arr variable is hoisted. The result is reference error.

[@skvalavideo]

Interview is wrong at 21:30 first thing is const don't support Hoisting and second thind for in return index as well with foo like 0,1,2,3,foo.

[@RaavNgaming]

Const is also hoisted but it goes into the temporal dead zone where we can't use the variable declared with const before initialisation

[@bishwajeetpandey1570]

Thank you for sharing such type of interview video , it help us alot

[@sayyedmoin3743]

Owesome perfect

[@chandansingh-sb3il]

[@subhamjaiswal8382]

Naa. This for 2year exp. Fresher mostly coding and basics

[@mudassarown6886]

Hey Aditya , why does in for of () loop , it doesn't give 5,6,7,8,"Hi" ????? Why hi is not shown even though we have set it. 🤔🤔

[@harshk7869]

we have passed hi value in an object not in an array

[@AbhayRai-t4e]

Because for of not works for objects ....

[@Theshoutoutuniverse1]

Almost each and every oquestion have an answer so google baba is actively helioing her 😂😂😂

I done many interviews before it's very hard to understand what's see is saying I had to play the video a few times. Also they over completed the question they just could of put it in comment and let the coder code.

[@DevAditya]

Hope it'll boost your confidence

[@sumitpanwar8804]

She was just doing google search lmao and that was the reason is was unable to frame the statements properly as she was just saying keywords after reading them on the google. But anyways questions were good.

[@karansahu4939]

she is reading it from somewhere. It can be clearly seen. Her pronunciation is very bad, still she is able to speak so fluently.

[@muhammadrazaullahansari6271]

I m 100% sure she is student of Akshay Saini, I used to answer in the same way
