I’m learning how to appending DOM nodes with Javascript and have a little clarification question. Here’s an example:

<html>
   <head>
   </head>
   <body>
   </body>
</html>

    document.childNodes[0]

So here, you would get the <head> node because it is the first child after the <html> tag. My question is can I always consider “document” to be the equivalent of the <html> tag or root node?

    I’d recommend studying the W3C DOM spec as well: even if some parts of it won’t mean much to you, it might save you a plenty of time and efforts later. )

    That’s what’s said about document here:

    The Document interface represents the entire HTML or XML document.
    Conceptually, it is the root of the document tree, and provides the
    primary access to the document’s data.
