React js developer interview coding Round |  

When i was a fresher these questions felt challenging now they look so silly :D

During the interview, the explanation provided by the interviewer could have been clearer. In the first console line, '5' + 3 results in '53' because the + operator performs string concatenation. In the second console line, '5' - 3 results in 2 because JavaScript is a loosely typed language, where the string '5' is implicitly converted to a number, allowing the - operator to perform an arithmetic subtraction.

+"12" instead of this we can write "12"-0 It also convert this value as a number

interview ❌ class ✅

Sir can you explain why you mentioned Selected? bcoz i dont think she will be selected if its an actual interview

0:27 53 and 2 i am saying this without running the code, i guess beginners should read Head First JS book it's really good book for basics

one day you ll show ur talent to everyone, just take it as this is also one of the practice.....good luck ma

HEllo word const arr = ["susman", "schahs", "dcnh","chuyd"]; let i = 0; function hello(arr){ if(i > arr.length-1){ i = 0; hello(arr) }else{ document.getElementById("header").innerHTML = (arr[i]); i++ } }

const names = ['Badal', 'Dipa', 'Farju', 'Anik', 'Sourof']; const heading = document.getElementById('hello'); let currentIndex = 0; const changeHeading = () => { // Change the heading's textContent to the current name in the array heading.textContent = names[currentIndex]; // Increment the index for the next click, and loop back to the beginning if necessary currentIndex = (currentIndex + 1) % names.length; } heading.addEventListener('click', changeHeading);

Agar interviewer has jaye interview me to smjh jao ho gya kaam tamaam interview ka 😂

what the fuck is happening here

good

I like how patiently he answered everything Kudos

javascript. js (file) const arr=["ABC", "Joy", "Raju"]; let count=0;//count clicks document. getElementById("hello"). addeventListener("click", function () { if(count

But the question is, how did she get selected? If there were a boy in her place, I don't think he would be treated the same

i can literally answer all the question but i am still jobless i dont know what to do

I am good in front end how will I got interviews

God this interview was unbearable, how am i unemployed and she got a job import React, {useState} from 'react' const ChangeName = () => { const [Name, setName] = useState("Dude"); const [Counter, setCounter] = useState(0); const NameArr = ["Amar", "Akbar", "Anthony"] const count = 2; const HandleName = () =>{ if(Counter

05:17 He said, it will convert either into number or into string, Which is totally worng, Interviewer either should say, check and reserch why and how its hapeening, he should not fire in the air.

Isko select kia tho main to selected hu bhai . Bakar ka main pressure la raha tha 🤣

This all were mock interviews not is just for practise not an real

How she is selected. She doesn't know coercion

Const array = [“a”,”b”,”c”,”d”] Const h1 = document.get elementbyid(“h1”) Var index = 0 function changename(){ Index= index === array.length -1 ? 0 : index+1 h1.textcontent = array[index] } h1.addeventlistener(“click”, changename) I wonder how those are get placed think this channel is just an institute

She will be a good developer soon.

Needs to practice more. Best of luck

That is a video only created for like an interview that's it

Anyone who support me to give react js developer job

i wish interview questions to be same in my country xD

Now Again 14:00 NaN === NaN gives false : His reasoning because it can come from any string. okay boss lets try with same string then, its should give you true then eright? let str='Hello' console.log(+str == +str ) // always false console.log(+str === +str ) // always false IDK know the actual reason, but commenting to know the exact reson and asking these type of interviewers not ask these type of questions or atleast give proper reasoning, or ask candidate to research about it.

const arr = ["test1", "test2", "test3", "test4"]; let count = 0; const hello = document.querySelector("#hello"); hello.addEventListener("click", () => { console.log("clicked"); if (count > 3) { count = 0; } hello.textContent = arr[count]; count++; });

console.log(11) Why first is true and second is false because true is equal to 1

Interview tha ya coaching session? upar se selected bhi.. 😂

At finally how to get print the array names in loop

bhai ye itna easy interview kon leta hai 😂😂 Mere se kitna tough questions pucha tha 🤐🤐

Help full Video for preperations

these are basic question these type question they are asking me as in not even as fresher round

if one is string then one is number.. in order for your to have numerical value.. you must put Number("5") + 3 UNLESS just a simple string

This class going on

4:12 1st one true bcz it's equal to, and 2nd one is false bcz it's strict equal to, to get true in === two value has to be same type and same value while for == if two value has different type then it's try to convert into same type

Plz dear sir provided interview in hindi

where do you get selected with this level of knowledge ?

itna hallu question me selection

sorry but sister dont even know how to declare variable what does it means to be selected ?

Flutter interview?

const arr = ["Hi", "raju"] let index = 0 document.getElementById("helloid").addEventListener("click", function(){ const studentsName = document.getElementById("helloid") studentsName.textContent = arr[index] index++; if(index >= arr.length){ index = 0; } })

const arr = ["A","B","C","D"] const target = document.getElementById("hello") target.onclick = function(){ let findIndex = arr.indexOf(this.innerHTML) let nextIndex = findIndex if(findIndex < 0 || findIndex >= arr.length-1){ nextIndex = 0 }else{ nextIndex++ } target.innerText = arr[nextIndex] }

If this was an interview.I will clear,Easily
