The provided JavaScript code creates a countdown timer targeting a specific date and time: June 2, 2024, at 1:16:00 AM. The timer updates every second, displaying the remaining time in days, hours, minutes, and seconds. When the countdown reaches zero, it stops and displays a message indicating that the countdown has expired.
Here is a breakdown of the code:
let countDate= new Date("june 2,2024 1:16:00").getTime();
This line sets the target date and time for the countdown and converts it to a timestamp in milliseconds.
let x=setInterval(function(){ ... }, 1000);
The setInterval function calls a specified function (function() {...}) at regular intervals (every 1000 milliseconds or 1 second).
Inside the interval function:
let now=new Date().getTime();
This line gets the current date and time as a timestamp in milliseconds.
let difference=countDate-now;
This line calculates the difference between the target date and the current date in milliseconds.
The remaining time is then broken down into days, hours, minutes, and seconds:
let days=Math.floor(difference/(1000*60*60*24));
let hours=Math.floor((difference%(1000*60*60*24))/(1000*60*60));
let minutes=Math.floor((difference%(1000*60*60))/(1000*60));
let seconds=Math.floor((difference%(1000*60))/1000);
document.getElementById("timer").innerHTML=days + "DAYS | " + hours + "h : " + minutes + "m :" +seconds + "s";
This line updates an HTML element with the ID "timer" to display the remaining time in a formatted string.
if(difference 0){ ... }
If the difference is less than zero (i.e., the countdown has reached the target date), the interval is cleared using clearInterval(x); and the HTML element is updated to show "Birthday Expires".
Overall, this code creates a dynamic countdown timer that updates in real-time and handles the expiration condition gracefully by stopping the timer and displaying a specific message.
