How to Create a JavaScript Interval to Run a Function Every Second?

In JavaScript, you can use the setInterval() method to run a function repeatedly at a specified interval. Here’s an example of how you can use setInterval() to run a function every second:

function displayTime() {
  console.log(new Date());
}

setInterval(displayTime, 1000);

In this example, the displayTime() function is defined and will be run every 1000 milliseconds (1 second) by setInterval(). The current date and time will be logged to the console every second.

Please note that setInterval() continues to run the function until it is explicitly stopped using clearInterval(). If you don’t need the function to run indefinitely, you may want to use a counter and clear the interval after a specified number of iterations.
