We can append child elements to another
element using the appendChild method. But
this way, we can only add the element as the
last child of the parent element. What if we
want to add an element before a certain element?
In the example given above, we have created a
new button element and inserted it at a
certain position in the page.
The insertBefore method is called on
the parent element and takes two arguments:
- The element that is to be moved or inserted.
- The element before which we want to place the newly positioned element.
