You already passed the kata, read this for the next time you post code, please: https://docs.codewars.com/training/troubleshooting#post-discourse

same with my code. Passing test but not attempt.

my below code passing test but not pass Attempt. Please help me to resolve the bug.

function persistence(num) {
//code me
//console.log(num);
if (num > 9) {
let valueOfMultiplication = num ;
// console.log(num);
let multiplicationCounter = 0;
while(valueOfMultiplication>9){
const convertedToString = valueOfMultiplication.toString();
// console.log(convertedToString);
let multiplicationVariable = 1;
let stringToInt;
for (i = 0; i < convertedToString.length; i++){
stringToInt = parseInt(convertedToString[i]);
// console.log(stringToInt);
if (stringToInt != 0) {
multiplicationVariable = multiplicationVariable * stringToInt;
}

          //  console.log(multiplicationVariable);
        }
        multiplicationCounter = multiplicationCounter + 1;
    //console.log(multiplicationVariable);
     valueOfMultiplication = multiplicationVariable ;
    }
    return multiplicationCounter;
   
}

else{
return 0;
}
}
console.log(persistence(7647280));
