Question 37 > There is no 'company' key in the 'student' object. So consoling an non-existing key should be undefined.

[omkaryadav]

Thank you for the video
Improvement should be done:-
1) Voice
2) add pdf in the description

[mazthespaz]

question 39. Couldn't you also move the array into a set then back into an array? I think a 4th method would involve a map

[tharangachaminda]

Simple explanation for Q37 is: "delete" will only work on non-inherited properties.

[shreykotharib]

Ans for 37 is not correct, what is .company? assuming it is typo and trying to console .college then also Object.create will create new reference and we are deleting key from new reference so output should be undefined not "abc"

[prashantmalik]

[KamlRomodan]

Q34> The output is "10undefined" and not "10function" can you elaborate...?

[davitkhoshtaria]

I don’t understand one thing, if only 5% of 95 using let or const why is var keyword is being used in interview questions

[mestrihimaja]
