Doubt in FizzBUZZ

#1

btnPrint.onclick = function() {

let start = Date.now();

let num = inpNum.value;

ulNumList.innerHTML ='';

function fizzbuzz(number) {

    if(number%3==0 && number%5==0){
        return "fizzbuzz";
    }
    if(number%3==0){
        return 'fizz';
    }
    if(number%5==0){
        return 'buzz';
    }
    if(number%3!=0 && number%5!=0){
        return number;
    }

}

for(let i=1 ; i<=num ; i++){
    let li = document.createElement('li');
    li.textContent = fizzbuzz(i);
    ulNumList.appendChild(li);
}

console.log("time taken ",Date.now()-start);

}

bhaiya , my code is running faster than Arnav Bhaiyas code.

Even though my code is not optimize like Arnav Bhaiya.

Nut in console my code is giving better resuly

I’m not able to understand why

#2

It maybe due to different laptop. Have your tried running Arnav bhaiya’s code on your laptop and then compare?
Also, if you are using different browser, then also results may vary.

#3

even I thought that…I did run Arnav Bhaiya’s code on my system…His code was taking twice what mine was.

Im not able to figure out how

#4

Can you send Arnav bhaiya’s code?

#5

btnPrint.onclick = function () {
let start = Date.now();
ulNumList.innerHTML = “”;

let c3 = 0;
let c5 = 0;
for (let i = 1; i <= inpNum.value; i++) {
let li = document.createElement(“li”);
c3++;
c5++;

let print = "";
if (c3 == 3) {
  c3 = 0;
  print += "fizz";
}
if (c5 == 5) {
  c5 = 0;
  print += "buzz";
}
if (print === "") print = i;

li.textContent = print;

ulNumList.appendChild(li);

}

console.log(“time taken”, Date.now() - start);
};

This is Arnav Bhaiyas Code.

I think it is because of usage of more variables and their frequent updation in loop.
Also, strings are being mutated in Arnav bhaiya’s code, which can degrade performance.

Either way, both are fine. The execution time difference is not very high.
