[@rajkirankelangi5751]

please make top 100 js coding questions. guys hit like buttom 🔘✅🔳

[@NikhilSingh-pb2jg]

First question.. Logic for doing in short way is wrong as after splitting using " " , we need to loop and then reverse.

[@OCEMTechZone]

🎉

[@interviewhappy]

Thankns

[@sandeeprathore7994]

Sorry but i cant get the Duplicate element question

[@manojhk7469]

join is not working sir

[@dineshkumarravichandran4981]

function larNum(){
const num = [1,2,3,4,5];
var laNum = 0;
num.reduce((x,y)=>laNum = x>y?x:y)
console.log(laNum);
}
larNum();

[@dineshkumarravichandran4981]

function primeNum(){
const num = [1,2,3,4,5];
var prime = num.filter((x)=>x%2!=0)
console.log(prime);
}
primeNum();

[@ArnabKhanrah]

In the 'IsPrime' function we need to add
If(number < 2){
return false;
}
Otherwise isPrime(1) will return true.

[@regilearn2138]

no need thats why the for loop started from 2

[@dineshkumarravichandran4981]

function fact(){
const num = 5;
var factorial = 1;
for(i=1;i

[@priyankasaini7204]

21:00 Using recursion
// Write a function to calculate factorial of a number.
// one way
function factorail(num){
if(num===1)
return 1;
return num* factorail(num-1);
}
// console.log(factorail(5));

[@kumaxFPS]

Q2 - can be done with REDUCE fx too !
const words = str.split(" ")
const ans = words.reduce(function(acc, curr){
if(curr.length > acc.length){
acc = curr;
}
return acc;
},"")
return console.log(ans)

[@priyankasaini7204]

17:00 Antother way
// // write a function to find the maximum number in an array
let arr= [2,4,56,7,2,100,5444,1,0];
function maxElement(arr){
return Math.max(...arr);
}
console.log(maxElement(arr));

[@giantbush4258]

These are fun to practice. That said these are not enough for first round. So i kindly disagree.

[@Raj_Panchalll]

const str = 'Hello world'
const reversedStr = str.split(' ').reduce( (acc, char) => char + acc + ' ')
console.log(reversedStr)

[@HangOut-BK]

//*check palindrome
