Bhai Can You Suggest Me,How To Get A Frontend Developer Job As A Fresher From Your Experience

[@shahhussain7192]

27:00 I think it is because of closures. When we use let keyword it creates scope of block i.e when the loop will be over than the variable created by let keyword "i" will be deleted but in between the loops block we have used an async function setTimeout in which a call back function is passed. and in the callback function we used a variable "i" of its parent scope in console log. so now it creates a closure in each iteration and saves its values than after it goes to web API environment one by one. so when all the execution is done within the loop than the async function is pulled back to the call stack through event loop. since each async function had captured the value of "i" in closures so it reflect in console log after execution. while in case of var keyword..... it is a global scope variable so it dose not delete though the loop has ended. So when async functions are puled back one by one to call stack via event loop they already had different closers value which were captured during iteration in variable "i" respectively but they get updated (re-assigned) to the last one because the value of "i" available in global scope. That is why it prints the same value i.e 10 ten times .

[@apurvajain7839]

Thats correct!

[@ashmitasharma2249]

Question tricki h but mazedar h mind fresh ho gya

[@amanrazz2091]

+1. I want to know the collective resources to learn indepth abstract concepts like these.

[@gauravparihar6962]

done and great work by @Piyush Garg.

[@poojamaheshwari748]

great explanation and u have given crystal clear every concept behind this question, please come up with more videos on javascript and react also

[@Arvind__-wu6zv]

31:00 Two doubts First one is : first line initializes fullname, so does this fullname doesnt become a part of global object?? Second one is : in case of iife does "this" doesn't refer to the current context?

[@moneylogyy]

same doubts i hve

[@Arvind__-wu6zv]

@@moneylogyy it's because declaring something with var doesn't make it a part of global object. It becomes more like a part of the module

[@moneylogyy]

@@Arvind__-wu6zv thanks bro

[@rahulchandak2772]

Great work man, thanks a lot! Really appreciate all the efforts :) Just one suggestion, if you could also give simple use cases after these interview answers, we'll be able to relate and understand better. Eg: where or why would one use Object.create etc.
