Difference between Node object and Element object?
...where the nodeType property has a value of 1.
So document.getElementById("test") can only return one node and it's guaranteed to be an element (a specific type of node). Because of that it just returns the element rather than a list.
Since document.getElementsByClassName("para") can return more t...
