Node.Js live interview session part-1

Sir please mention in the title it's was for experienced workers.. I almost shat my pant as a fresher.

The OPTIONS method can be implemented by adding a route to the API that responds to requests with the OPTIONS method. The response should include information about the allowed methods, supported headers, and other capabilities of the API.

Please upload more videos on nodejs interview. This one I liked.

If a request and response are from different ports on the same server, the web browser will see them as coming from different origins, and CORS will be triggered. In this case, the server needs to send the appropriate CORS headers to allow the web browser to access the resources.

UPDATE table_name SET gender = CASE WHEN gender = 'male' THEN 'female' WHEN gender = 'female' THEN 'male' ELSE gender END;

update user_profile set gender= if(gender='male','female','male') or update user_profile set gender= case ( when 'male' then 'female' else 'male' end)

Different protocol, different domain, different port will happened cors issue.

Sir can you upload more vedios node js

update user_profile set gender=( case gender="male" then female" else "male" end)

Update User_Profile set gender = (case when gender = 'Male' then 'Female' else 'Male' end) ;

UPDATE [EMPDATA] SET GENDER = (CASE WHEN GENDER ='MALE' THEN 'FEMALE' WHEN GENDER = 'FEMALE' THEN 'MALE' END )

why do I think he is cheating, in fact, I can screen in his specs on various timestamps, and his eye is moving to that screen regularly.

Update user_profile set gender = (case when gender = 'male' then 'female' else 'male' end) ;

Some of the questions i don't think will be asked from a 2-3 year experienced js dev

Find by I'd and update method

He is selected?

Pura theory based questions kon karta hae bhai 5 years experience mae . Ap simple PUT and Patch nahi janti ho nodejs ka acha se para but e sahi nahi e .. Aise technical interview nahi hota e acha skills set banda ka liye nahi hae

Is the candidate selected?

Put:- it used to create/update the resources(data).but if u update particular field, the output is particular field only remaining fields will be deleted. Eg:- { "name":" ABC", "age":90old, "place":" M.G.Road", } If used put method to update (age field) . {"age":"90years"} output is :- {"age":"90years"}. patch :-it updates only required fields(resource).eg:- If used patch method to update (age field) . {"age":"90years"} output is :-{ "name":" ABC", "age":"90years", "place":" M.G.Road" }

It's seems that questions are so tough or may be this video is not for freshers.....?
