What happens when the user sets an alarm when the countdown is already running?

clearInterval(myInterval);
const userInput = document.querySelector("#alarmSet").value;
let timeRemaining = Number(userInput);
if (isNaN(timeRemaining) || timeRemaining <= 0) {
alert("Please enter a valid number.");
return;
}
myInterval = setInterval(function () {
timeRemaining -= 1;
const minutes = Math.floor(timeRemaining / 60);
const seconds = timeRemaining % 60;
const formattedMinutes = String(minutes).padStart(2, "0");
const formattedSeconds = String(seconds).padStart(2, "0");
const charactersLeftP = document.querySelector("#timeRemaining");
charactersLeftP.innerText = `Time Remaining:${formattedMinutes}:${formattedSeconds}`;

if (timeRemaining === 0) {
playAlarm();
clearInterval(myInterval);
}
}, 1000);
}
