In fact JavaScript way of doing this is very bad.

Consider this:
  div::before { content: ""; }

Empty string is valid value of the content so you cannot assign empty
string to nullify/undefine that property

JavaScript shall use on of these constructs:
  el.style.prop = null;
  el.style.prop = undefined;
