childNodes returns collection of child node.
If you put whitespace after parent element then that would be consider as text and this text will be a child node.

So actually you have whitespace as a child node at 0th position.

Try to remove whitespace after opening div then you will get how it is working.

Answer 2

to get only list of html elements (not the text nodes), you could use 'children' property instead of 'childNodes'...

as the returned array-like is dynamic, removing one element will remove it also from the children list ^^

so, you must remove first higher indices to lower ones:

window.onload = function() {
var parent = document.getElementById("demo");
var child = parent.children;
parent.removeChild(child[1]);
parent.removeChild(child[0]);
};

alternatively, you could use twice the index 0 ;)
