I am executing setInterval(myFunction, 10000); to invoke a function every 10 seconds in JavaScript. Can this repeated execution be terminated based on a specific event? I aim to give users the ability to stop the continuous data refresh.

To halt the execution of a setInterval in JavaScript, you can employ the clearInterval method. This function stops the ongoing interval when you call it using the interval’s ID, which is returned by setInterval. Here’s a practical example:

// Start setInterval and store its ID
const intervalId = setInterval(myFunction, 10000);

// Function to stop the interval
function stopInterval() {
    clearInterval(intervalId);
}

// Assuming there's a button to stop the interval
const stopButton = document.getElementById('stopButton');

// Link the function to a button or event
stopButton.addEventListener('click', stopInterval);

In this example, setInterval starts the repeated execution of myFunction every 10 seconds. The intervalId is used by clearInterval to halt the process. The interval is stopped when the user clicks a button identified by ‘stopButton’. You can tailor this to stop on any event by replacing the event listener.
