Stop-Watch App Made Using Vanilla JavaScript

Hello Ladies & Gentlemen,

Introducing The Stopwatch App :

A powerful time-tracking solution developed solely with vanilla JavaScript. With an
elegant design utilizing Bootstrap CSS, this app provides a seamless user experience.
Effortlessly track elapsed time with start, stop, and reset functionalities. From its
clean interface to precise timekeeping, this app demonstrates the versatility and
effectiveness of JavaScript in creating interactive web applications.Embrace the
simplicity and functionality of this stopwatch app today and take control of your time
management needs with ease.

In order to create the stopwatch app using vanilla JavaScript, I followed a
step-by-step approach. Here's a summary of the steps I took:

1. HTML Structure: I started by creating the basic structure of the HTML
page. I added a container div with a title, display area, and buttons for start,
stop, and reset.

2. CSS Framework: I used Bootstrap as the CSS framework to style the HTML
elements. I included the Bootstrap CSS file in the HTML head section using
the provided CDN link.

3. JavaScript Variables: I declared variables to store references to various
HTML elements, such as the display area and buttons.

4. Timer Functionality: I created variables to keep track of the start time,
elapsed time, timer interval, and running state of the stopwatch. I also implemented a function to format the elapsed time into the HH:MM:SS:MM
format.

5. Update Display: I defined a function to update the display area with the
current elapsed time. It calculates the time difference between the current
time and the start time and formats it using the formatTime function.

6. Start Timer: I implemented a function that starts the timer when the "Start"
button is clicked. It sets the start time to the current time, starts the timer
interval, and sets the running state to true.

7. Stop Timer: I created a function that stops the timer when the "Stop" button
is clicked. It clears the timer interval, calculates the elapsed time by adding the
time difference between the current time and the start time, and sets the
running state to false. When the user clicks the "Stop" button, the current
elapsed time of the stopwatch will be stored and displayed as a list item below
the stopwatch display area.

8. Reset Timer: I implemented a function to reset the timer when the "Reset"
button is clicked. It clears the timer interval, sets the display area to
"00:00:00:00", resets the elapsed time to 0, and sets the running state to
false.

9. Event Listeners: I added event listeners to the buttons to trigger the
respective functions when clicked.

the HTML elements are loaded.

This approach allowed me to create a functional stopwatch app using vanilla
JavaScript, without relying on any external libraries or frameworks for JavaScript.
