// Create a number formatter to print out on the UI - this is a better approach than regex IMO.

//Read this blog for more on event delegation and why it's useful: https://davidwalsh.name/event-delegate
checkboxContainer.addEventListener('change', e => {
  //Also notice that I am listening for the change event, instead of the click event.
  //See here: https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/change_event

<!-- Notice I added a parent div to enable use to use event delegation technique -->
<!-- Also notice I removed element id attributes where they were not needed. Also be sure
to always use unique id values for every element - duplicate ids are not allowed, it will 
lead to bugs. If elements need to be considered part of the same "group" then you should use
the class attribute. -->
