I understand how to implement a single click counter. However, I am struggling to figure out how to implement a button that will duplicate the click counter, while also allowing me to use the same javascript code.
My current layout for a single click counter has a div for the counter then a button for incrementing and another for decrementing. For the buttons, I am using a separate event listener for each one.
<div id="counter">0</div>
<button id="increment">+1</button>
<button id="decrement">-1</button>
Javascript:
var incr = document.getElementById('increment');
var decr = document.getElementById('decrement');
incr.addEventListener('click', ...);
decr.addEventListener('click', ...);
How would I implement another button that would copy the counter? Also, how do I approach the javascript side? My current approach does not seem to generalize well for multiple counters.
