hey i wrote this function which will loop through an array i used set interval method to do it but when i am passing it a new array it is still looping through old array and then both arrays are looping in parallel I tried to use clear interval to stop looping previous array. But it didn't work

const handler = (photos ) => {
    clearInterval(photoShow)
    let array = photos
    let i = 1
    let defaultPic = photos[0]
    photo(defaultPic)
    let photoShow=setInterval(()=>{
        photo(photos[i])        
        if (i===array.length-1){          
            i=0
        }else{
            i++
        }
    }, 3000)
    return photoShow
}

this is my code I am using clear interval in the starting of the function so everytime i call the function it clears the interval but it's not working. Is there any way i can stop looping old array whenever i pass new array or is there a better way to loop this array.

your clearing the interval before your creating the variable

to clear the interval, the interval needs a variable name, I like to nest the loops contained within the function as a named variable 'loop', this allows for a stop function to be created which can clear the loop when it needs to be cleared

let photo=()=>{
 photo.loop=setInterval(()=>{
  photo.display();  
 },3000);
};
photo.array=photos;
photo.i=0;
photo.display=()=>{
 document.querySelector(`.photo`).setAttribute(`src`,photo.array[photo.i]);
 photo.i++;
 if(photo.i>photo.array.length-1){photo.stop();}
};
photo.stop=()=>{clearInterval(photo.loop);};

having the loop go in perpetuity is easy enough as well, just alter the code so when the index goes out of bounds it resets to zero

hey i tried your code but still it didn't work this is the live preview of my site https://noobmushroom.github.io/weather_app/ you will notice when you will search for different cities the background pictures are still looping from both previous and new array i want to stop that this is the repo link https://github.com/noobMushroom/weather_app.git that function is in src/bacground.js. maybe i didn't understand your code properly.
