Thank you so much for this video. I have just one request, I understand revenue generation is important from ads after so much of hard work but please keep some fewer ads as it breaks the flow.

[@codestepbystep]

Bro, Ads are auto managed by KZbin not by me 😊

[@santoshgautam819]

Rat ke 3 baje vidio shoot kar rahe ho ap.. Thank you so much .ye video bhut helpful hai really and I don't skip any ad because I know you are doing so much for us, so we should also give something in return That's why whenever the ad is coming, I take rest or check the same question again.

Hey Anil. Thanks for such a wonderful video. Last year, I have learned react from your channel and I got my first job as a frontend developer because of your course. Now again , I am looking for a job change and I came here to your channel for interview preparation and in mid of learning i thought to write an appreciation for your work. I have gone through your DSA full video and found it very amazing. You told everything in such a manner ki sabko samjh aa jaye. 😊 I really appreciate your work and happy to learn from you. 😇

8:00 bhai ye spread operator h, Destructuring and spread m difference h: Destructuring s variables m array ki specific values extract kr skte h; spread s khol dete h array ko ar saari values aa jati h fir chahe use dusre array m daalo ya console m log kro.

[@AnujSharma-kd9so]

In q no 48 it is undefined because var is initialised by undefined when code read by compiler. "Console.log(a) Var a =30" Is also undefined as output

[@mohdsahil226]

Excellent ! Please explain some coding questions. I do all those array and object questions, but i forget at the time of interview. Do you have a trick so we don't forget them like Binary search, circular linked list, graph data structure questions! I am even ready to pay! Thanks again for your efforts!

[@dashingvir2058]

thank you sir u built my confidence in js ..i subscribed you $$$

[@manishdalal5951]

Question 85 Explanation: First we created object somewhere in memory referenced by variable named person, lets say that object is created at address 0x1234. Then we defined another variable named 'members' which points to an array whose first element is pointing to the person object. So members[0] is pointing to the same address as person object (i.e. 0x1234) After that we set person to null, so now the person variable stores null value (ZERO (0) in most programming languages). But members variable still points to the array in memory whose first element still points to address 0x1234 where person object is still stored.

[@rajeshsukheja4802]

what about question 86.... can we iterate object (VSCode error :'CAN NOT ITERATE OBJECT")

[@mrwhispersofficial]

@@rajeshsukheja4802 you can use for in or for of loop

[@travel2react567]

I have given a lot of interviews on Java-script recently, and trust me guys, these are the exact questions they ask in interviews. You will not find such a video on the whole of KZbin. @code_step_by_step, It will be amazing if you will provide a pdf for the same. it will be really really helpful for revising these topics.

[@siddharthsingh913]

So are you saying the interviews are easy? Because these were very basic questions if your basics are clear.

Question No :- 56 , Time :- 1:14:10, Problem :- I am confuse with first option , Answer :- console.warn ( bird [data] ), Output :- SMALL

data = "size", so when u write bird[data], it is equal to bird["size"]

bird[data] , here inside square brackets, the variable is evaluated as its value is initiated to "size" it equals to bird["size"]

[@FaizanAnsari-yg1gw]

first = 'usa' second = 50

[@alkabhardwaj4314]

​@@FaizanAnsari-yg1gw how?

[@indian-shorts9215]

@@alkabhardwaj4314 var is global scope variable you can redeclare it in whole js code anywhere

[@0-0-0-0-1]

​@@alkabhardwaj4314 the output for num is 50 because he has again declared num inside curly braces and these curly braces are not associated with any function or control statement. So, this variable num will be hoisted to the top of global scope and hence the value of num will change to from 23 to 50.
