1. Reads the value from the input field (1a)
2. Removes the <input> and <button> tags (1a & 1b)
3. Creates a new <p> tag, initialized to show the input value
4. Starts a timer that ticks down to zero. For every second that elapses, the paragraph tag (2c) will show the updated timer value (i.e., one less)
5. When the timer reaches zero, the countdown will stop and the paragraph tag (2c) will be removed and be replaced by a <button> tag labeled "New Timer"
6. When the <button> tag (2e) is pressed, it will be removed and the <input> and <button> tags (1a, 1b) will be recreated with their original formats
