Countdown Timer

Problem

Timer interfaces look simple, but they force you to handle state, time updates, and user controls cleanly. This made it a useful early JavaScript project.

What I Built

Countdown Timer is a browser-based timer application built with HTML, CSS, and JavaScript. It covers the core interaction loop of starting, stopping, and displaying time changes in the UI.

Technical Decisions

I kept the project dependency-free so the focus stayed on DOM updates, interval timing, and responsive layout fundamentals.

Outcome

The project helped establish the basics of client-side state management before moving into larger React applications.
