JavaScript Countdown Timer Tutorial | Date, Intervals & DOM Updates
Welcome to Day 10 of my 30 Days of Coding Challenge!
In this project, I built a Countdown Timer App using JavaScript. It dynamically calculates the time difference between now and a target date using the Date() object and updates the UI in real time with setInterval().
💡 What I Learned:
How to use the Date() object to handle time
How to calculate remaining days, hours, minutes, and seconds
How to use setInterval() for live updates
How to format output for a clean countdown display
💻 Tech Used: HTML, CSS, JavaScript
🚀 I’m building one project each day for 30 days straight!
