Release 0.3:Remove Duplicated Code for Removing Section

In this code modification, I tried to make the code look simpler, so I optimized several of them, so I created a class that makes it easy to maintain updates later, which is easier to do. Arrived:

Html: DOM(document.getElementById)

Javascript:array(array.foreach method)

Javascript: code refactoring – elimate repeat code to make code easier to maintain

Css: element style: display attribute

 

Html: DOM(document.getElementById)

The Document method getElementById() returns an Element object representing the element whose id property matches the specified string. Since element IDs are required to be unique if specified, they’re a useful way to get access to a specific element quickly.

If you need to get access to an element which doesn’t have an ID, you can use querySelector() to find the element using any selector.
