appendChild + createElement

Question

What\'s the difference between:

var div = document.createElement(\'div\');//output -> [object HTMLDivElement]

document.getElementById(\'container\').appe         


        

Answer 1

appendChild really does expect a HTMLDomNode of some kind, such as a HTMLDivElement, and not a string. It doesn't know how to deal with a string. You could do

document.getElementById('container').innerHTML += div;

but I really prefer the first version; and I'd rely more on it to behave the same across browsers.
