Wow FND! I could have never guessed. Thanks!
Its here too at https://developer.mozilla.org/En/DOM/Node.appendChild:
var appendedElement = element.appendChild(child);
The returned element is the child which is *appended*. So this line
does NOT return element "p", it returns the helloworld textnode.
document.createElement("p").appendChild(document.createTextNode
("helloWorld"))
Is the element "p" being created? I would hazard a guess that it *is*
being created. But in the following line the element p is not appended
to the body but is left orphan, and the returned appended child text
node goes on further to be appended to the body element in this line:
document.getElementsByTagName('body')[0].appendChild
(document.createElement("p").appendChild(document.createTextNode
("helloWorld")));
The next logical question is what does the above line return? The
helloworld Textnode still!
Thanks to FND for this again.
