Let’s look at some of the JavaScript functions we have used to handle the functionality of the stopwatch. The function startStopwatch() gets the current time in milliseconds using new Date().getTime(), and starts an interval using setInterval() to update the stopwatch display every second.

Before we start coding, here’s a quick checklist of what we’ll use: HTML: For creating the structure of the stopwatch. CSS: To style our stopwatch and make it look nice. JavaScript: To add functionality like starting, stopping, and resetting the timer. You can use any text editor and a web browser to see your progress.

We have written a simple HTML code to display a stopwatch on a web page. The HTML code includes a <div> element with an attribute id set to the stopwatch, which will display the current time. Then, we have created three buttons, “Start”, “Stop”, and “Reset”, using the <button> element. These buttons will be used to control the stopwatch.

Create one container in which all the elements are present. Inside this container, add 2 divs that contain all time elements like an hour, minutes, seconds, and milliseconds, and another div contains 3 buttons for start, stop, and reset the stopwatch. Now add Styles to center the div container.
