It is also know as short circuting in which if 1st expression is true then 2nd expression will never be executed. And same things also works on and operator in which if 1st expression is false then 2nd expression will never be executed

@midhungopi4736 2 месяца назад

Thanks...I don't know that it has a fancy name I thought if it's an OR operator and it's true then checking the 2nd condition doesn't make any sense irrespective of the result it's any way output true as the first one is true that's why the compiler being smart skip the 2nd condition and returns true 😅

@user-qv8ve4dc9k 25 дней назад

i thought that would return true or false, wjy did it return the actual value ?

That is not a bug. Works correctly. If person gets 0, he is absent for exam.

What about he appears for the exam and did not solve any questions ? Absent and getting 0 is two different scenarios

If recruiters are asking questions about javascript errors which are to be visible with right in the editor using typescript. This is missing the point of reliability.I think they should ask questions based on typescript type system

Sir 2 din se lexical scope padh raha hu kuch samjh nhi aa raha h Function scope aur lexical scope me difference kya h aur Lexical kya h

@rahuulmiishra 2 месяца назад

lexical word ka matlab hota hai fixed. and lexical scope means a scope which is fixed. ab ek scope fixed kab hota hai? jb hum code likhte hai. code likhne k time pe hi jo scope variables ka hota hai wo lexical scope hai. lexical scope code likhne k time pe picture me aata hai… lexical scope k andar function scope global scope ye sab aate hain.

@user-qv8ve4dc9k 25 дней назад

the output is wrong, according to both gpt and gemini, absent would be returned only if the left side value is null or undefined, here 0 is neiether null nor undefined making it return 0.

please don’t trust ai blindly. run this code in console and check

@user-qv8ve4dc9k 25 дней назад

@@rahuulmiishra no, check mdn documentation, nullish coescaling operater (??) returns rhs value only n only if lhs value is null or undefined. the point of ?? operater is to propogate || or operater functionality while only considering null n undefined as falsy value, values like empty string, 0 etc are still considered truthy value in ?? operater

@user-qv8ve4dc9k 25 дней назад

@@rahuulmiishra you passed 0 as paremeter in the function which represents lhs vlaue in expression, and is NOT null or undefined, so technically it should return 0 instead of absent string.
