Some problems in Looping.

1.Multiples of 3 and 5 Code: let i=1; while(i<50){ if(i%3==0 && i%5==0){ console.log(i); } i++; } What the code is doing: - It Start from i = 1 - It Will Loop until i < 50 - Check if i is divisible by both 3 and 5 - If yes → Then it will be printed - Increase i every time Screenshot of the Program: 2.Prime Number code: let count=0; let num=5; let i=1; while(i<=num){ if(num%i==0){ count++; } i++ } if(count==2){ console.log("It is a PrimeNumber") }else{ console.log("It not a PrimeNumber") } What the code is doing: - Start with i = 1 - Loop until i <= num - Check if num is divisible by i - If yes → increase count - Increase i every time - After loop ends: - If count == 2 → print Prime Number - Else → print Not a Prime Number Screenshot of the Program: 3.count of digits Code: let num=12345; let count=0; while(num>0){ num= Math.floor(num/10); count++; } console.log(count) What the code is doing: - Start with num = 12345 - Start with count = 0 - Loop until num > 0 -
