I have around 2.5 years of experience in MERN stack Recently I started giving interview interview questions 1)what is web workers 2)what is aws-node js architecture 3)explain microservices in node js? Have you ever used? 4) custom hook( I wrote custom hook with long polling concept) 5)middleware in backend? Problems 1)leap year with out using inbuilt function 2)remove duplicates and sort an array without using in built Even answering all I got rejected 😢 because I didn't have any experience on payment methods like razor pay implement or pay tm implementation

I would appreciate the interviewer too for asking real world practical questions which is oftenly faced in development, simultaneously testing the thought process and the problem solving approach.

@saurabhkumarjha4996 Год назад

This video has helped me a lot practicing my JS questions, by the way they did not ask much JS and asked only angular. This channel's angular videos specially the cognizant interview was very sharp and gave me resolution on how to study and what to study, watched nearly every videos here and the interviewer has very sharp concept clearance. Gave me a boost in my confidence to sit and be confident while answering. The main thing while the interview was happening is, I was asked nearly everything from CSS, SCSS, Angular and git. Git was nicely answered, but angular questions was half repeated from the cognizant interview video and globant video. Thank You pawan, for helping me and giving me the confidence I wanted to excel the interview. I cleared my first round successfully, and preparing for the next round. Thanks!! Again !!

How to manage nested routes terms of role based routing? In session we store token of user which will get us role of logged in user through API. We can store this role in context or redux state and then by the help of selector we can get access value from state and add route only if user has the access to that particular page ex: {hasAccess && }

@Nikhil-qd9up Год назад

Had a quick question,what was exactly the question for getting output 1,2 without using let? I think without using setTimeout also by only using var it would have given the same output as 1 2 Please let me know if i missed anything

@uidevguide Год назад

Hi Nikhil, the question is for how you know event loop and how setTimeout works and when it will execute, without setTimeout this question not makes sense, Please try to create multiple scenarios for such question it will help you in your interview process

I dont understand between map vs filter..both are creating new array then what is the difference between these..

@uidevguide 7 месяцев назад

Map: returns an array of pieces of information from the original array. In the callback function, return the data you wish to be part of the new array. Filter: returns a subset of the original array based on custom criteria. anyone here to contribute more

@husler7424 Год назад

map and filter return new array, so it won't affect the original array even if we change the result of them. How come mutability and immutability here?

Hi , I have a doubt in shallow copy answer. Shallow means if we do any change in obj1 it will reflect new obj.Right?. You said shallow copy 1. const obj2 = obj1[normal way] 2) Spread Operator 3) Object.assign these are ike shallow copy. But by using Spread Operator, I tried please correct me if am wrong. const emp1={ eid: "E102", ename: "Jack", eaddress: "New York", } const emp3 = {...emp1}; emp3.eaddress = "US"; console.log(emp1); //o/p:{eid: 'E102', ename: 'ashu', eaddress: 'New York'} console.log(emp3); //o/p:{eid: 'E102', ename: 'ashu', eaddress: 'US'} emp1.eid = "E108"; console.log(emp1); //o/p:{eid: 'E108', ename: 'ashu', eaddress: 'New York'} console.log(emp3);//o/p:{eid: 'E102', ename: 'ashu', eaddress: 'US'} please explain?
