About the Alarm Clock and Timer Web Application

The Alarm Clock and Timer Web Application Project displays a live date and time. The user can set up a timer with a duration of their choice. The timer displays on a card or a panel in the screen and when the user clicks the start button, the set timer duration will start, and the pause button will show. When the timer meets the "00:00" value, the application will loop and play timer audio and will be only stopped when the user will reset the timer. Users can set multiple alarms in this application. The set alarm data will be stored in the web local storage. The alarm feature also has audio. The alarm items can be also deleted and this function has a confirmation feature.
