IDK maybe i am being greddy but do think on it if u time sir. thank you BTW for your amazing video loved it

[@narendra3385]

You can miss Asynchronous JavaScript like callbacks and promises, timeout functions

[@keerthanaanandan6062]

One more thing I would like to add 1+1+”4” gives 24 “4”+1+1 gives 411 Js works from left to right and if the starting is string then it takes upcoming values as string as well

[@stfgaming2022]

thanks bro

[@vens-tech-world]

"200"+(2+3+4) "2009"

[@chinmayjain9705]

1+1+ +'4 '= 6

[@ganapathilana7069]

Thanks for detailed Q& A. Good clarity in list : 1. dynamic language. 2. Hositing behavior, 3. global variable, 4. use strict, 5. closure, 6.IIFE 7. design patterns 8.create object - 9. Inheritance - prototypal inheritance. 10. let keyword - temporal dead zone. 11. let vs var

[@nethajimurthy1229]

If you were my mentor, i will have the potential to get into any company as i prefer.... God level details... Now my confidence level is 100% thank you so much... And that closure concept is mind blower

[@Shri_Hegde]

Thank you for this video. Please make video of React js interview questions

[@kevingrimaldi6012]

Hi! On regards to inheritance, correct me if I'm wrong... You can also do inheritance by class using the "extends" keyword. So I believe that is important to mention, or maybe I missed that part.

[@Gurralanarayanareddy]

I think extends keyword we use when we use ES6 syntax when we use classes. but here the mostly plain JavaScript inheritance, that is the reason it is mostly on prototype i believe.

[@PallaviDwivedi-xp3gy]

This video is Gold for interview prep. It gives you clarity on the concepts so that you don't just blabber things during the interview.

[@raxitlakhatariya5915]

[@tonybaker8971]

i love your courses - very concise and pretty broad ranging

[@pahlavedaniel4992]

Bro, you are an amazing programming tutor. Thank you 👏

[@ranjithanaikp]

Hello sir, I am having doubt on normal and IIFE function. To avoid name collision we can use IIFE, but IIFE is a function which is invoking immediately once page loads right? So what if I want a function which I don't want to immediately invoked but should not have name collision? So which function I should use now?

[@BabiSushmaTour]

sir your way of explanation is so easy to understand thanks for the video🙏

[@SathishKumar-ju7fv]

[@vassudevc8354]

Thanks a lot Sir. 🙏👏

[@coder-webdev5907]

Write a function called do_allocation(number_of_people, number_of_buses) The function should return a list of number of people who can get into the next bus that comes in based on the following logic: Each bus’s capacity is the sum of the capacities of the previous two buses. Once all the people get in, then the buses can continue, but will have 0 people inside it. This is the case when the number of people are less and there are more buses. So after all the people are already boarded, then the remaining buses will have 0 people boarding. The output of the function is an array/list with the same length as number_of_buses. The total of this output array/list should be less than or equal to the number_of_people. The first bus’ capacity can be set to 1 by default. E.g. Def do_allocation(number_of_people, number_of_buses): …. Your code…. Return array[number of people got into first bus, number of people got into second bus, …. , number of people who got into last bus]

[@TheOMarsawy]

[@questpondvideos]

JavaScript Q&A Part 1 to Part 4 you can avail from here www.questpond.com/javascript-interview-questions-and-answers/cid87

[@rahulsuthar8590]

I suppose undefined means variables is being declared but type is not defined and null means variables is defined with the type was well but the value is not set yet. Example : var x --> undefined. no type defined yet var y = null -> type is defined but the value is null. Please correct if I am wrong

[@jatindermahal11]

Actually, undefined is itself a type in javascript. So, in var x; x would still have a type and that type is undefined.

[@jatinnandwani6678]

Thanks so much

[@amitvyas2386]

Hi, on the question of what is the difference between a normal function and an IFFE, can I say that a normal function is not necessarily executed immediately?

[@lishna4200]

[@Neerajvlogs-pn9eo]

[@vanshpal5960]

best

[@vishwankvrai]

43:25 what is that last para..and your definition is different from what's written

[@imyounick]

What is difference between below code without IIFE i can achieve same thing with below code var namespaced = function IffeFunc() { function Customer() { return "Some customer" } function CustomerInvoices() { return "Invoices" } return { Customer } }; let name = namespaced().Customer(); // "Some customer"

[@jhaeberli]

Thanks for the video. 'use strict' does more than just checking for var variables. If anyone is interested, google it ;)

I don't get why in video created in 2022 we still see a "var" ??? I believe no-one is using it anymore, or am I wrong!?

[@questpondvideos]

Its a interview questions video and later we have talked about difference between var vs let. FYI Devs still use var , it has its own place.
