One of the main difference is that by binding events to "document"
node ensures you can attach handler code as soon as possible without
having to block the load waiting for some signal that tells you can
start.
Binding to the "body" element will need an "onload/ready" event to
ensure the "body" is present, this requirement alone, in turn,
normally forces people to use a library when not strictly necessary.
Obviously $(document) and/or $('body') also presumes a lot of code is
needed to select the elements through a selector engine when for the
simple case outlines it would have been easier to access them
directly.
