really good video to learn more about js
My name, my state ❤, useful video sir 🙏
Hey Vasanth, thanks a lot for creating such great videos on interview.
Yesterday I cracked a very good job as a frontend developer all thanks to you ❤ Keep up the good work!!!
If it's possible I want to give a mock interview with you, that would be a great experience.
This weekend I'm planning to take free mock interviews, keep checking posts on TH-cam and be a part of my Telegram group here: t.me/uncommongeek so that you can book a slot.
Instead of following this questions just make ur basic clear follow namaste javascript playlist will able to crack any javascript interview

I have a more detailed playlist, give it a shot
1.Why polyfills, browsers without the latest advancements in the language, need to implement the advancements methods in older syntax that browsers can understand ,
Please correct me sir
Right answer !!
@@careerwithvasanth thanks for replying sir 🙏
Bro iam learning frontend development from last 8 months but for me Javascript looks like, it feels bihord what can I do

No way he's a 3 yrs exp js/react dev
you are 4y exp, I will ask 10 var complicated question you wll get confused, dear Just see 10:15
@@WebBlows It wasn't that complex believe me. And not being able to write polyfill for map shoes the picture clearly. Dont need to get hyped over the comments blaming the interview process its just about testing the critical thinking in a pressurized environment.
@webBlows This question are very common to test ur fundamentals just clear basic
polyfile is cross browser compatability right?
absolutely correct !!
Your interview questions are really helpful to me
But tell me answers with examples that's better to know us
Please make a series on those
Like how js works on browser?
Give answer for this and with ex
It's better to know us
Geezzz, You heard him right he said "I think promise is async Operation". 8:41 Promise is an async operation without a doubt, how he is fetching data. im literally frustrated. 😊
hi @vasanth is there any mockup interview for upcoming weekend , i would love to part of it . paid one is also good to me.
topmate.io/vasanth_bhat you can always set up a session with me here
@@careerwithvasanth sure will ping you in linkdin 1.8k is too much rt now for me .Thanks.
Why do you need to conduct a separate interview, just listen to his questions and pause and try to solve them by yourself, as simple as that. Do this for 10-15 other mock interviews on TH-cam and then you would be ready
The disparity is significant when comparing learning JavaScript for interview preparation to understanding how it fundamentally operates.
That's true !!
and this question is for interviewer
Please tell me the output sir,
and why ?
please
var aa;
if (1) {
console.log(aa, 1)
aa = 15;
function aa() {}
aa = 10;
console.log(aa, 2)
}
console.log(aa, 3)
function aa() {}, 1 //it will hoist on top of if scope and won't replace variable aa which is outside, because while logging it still find aa in its scope then beyond scope
10,2 // now we are reassigning that function hoisted inside if block with aa=10 thus it is printing 10,2
15,3 // since function did not replaced the outer variable, aa = 15 value will be assigned to outer variable because if you go through the code it still referring to outer aa, try to remove function aa() {} line and add var aa from outside to inside above the console.log(aa, 1) line you will get what I am trying to say.
@@arb2275 thats what my questions
if ''aa = 15 value will be assigned to outer''
why not 10
@@WebBlows i also want to know this
why you confuse candidates by using var, who uses var ? either it is 3y or 4y exp, I am asking why? ask practical questions..
I can ask 100s of questions this interviewer will get confused over var and ;et hoisting...
Ps. this I am writing because you aksed this 10:15 question to him.
He has 3 years of experience and then you are saying he is confusing him. ?
Asking var question to evaluate a 3yr experience dev is dumb. Does your company have legacy code to be asking questions about something that is not being used for years?
Thank you both for justifying my approach !! it is not always about what work they would, it's more on how they think and how strong they are fundamentally, so such questions are asked in the interview.
I know sir,
this queston is making me wrong everytime,
thats why I sad dont ask var , for hosiitn its okay, simple question , but in modern days no one uses var, so going deeper and asking var var is not good , like wise you can ask 100s of snippits evryine will get confused.
for example
can you try answering this please
var aa;
if (1) {
console.log(aa, 1)
aa = 15;
function aa() {}
aa = 10;
console.log(aa, 2)
}
console.log(aa, 3)
PS: Sir 🙏, I really want to understand this

WTF ! He doesnt know polyfills and he has 3 yrs of experience. I've seen upto 4:15 and Here's my answer for that question.
We need to implement polyfills if we have some user base in old browsers like Internet explorer or some other old browsers because the old browsers doesn't support some built in methods and it might impact the user interface or deliver bad user experience. In that case we need to implement our own implementation of that built-in method to fix that. But developers dont need to worry about that if they use Babel or some other tools. It implements polyfills for us by converting each and every buil-in method we usedbin our code to custom functions
