I haven't read the whole draft yet so maybe it's in there, but can you,
or anyone else, explain why there is both a selectElement and a
selectAllElements method?
I'm no authority, but:
If you know you're after one element, you get to deal with it directly
rather than first referencing the only contents of a single-element
array.
But document.selectAllElements("#first")[0] would do the trick.
That's not a big deal, I suppose, but a some benefits are
reduced and more readable code (i.e., reading through the code would
make it obvious that only a single element was desired in any given
case).
True, but you can also make this obvious by choosing descriptive names
for your variables.
Also, it sort of provides a correlation with getElementById,
and while I find the symmetry somewhat appealing, I'm not sure if that
motivated anybody's thinking.
But there neither are singular versions of getElementsByTagName and
getElementsClassName.
If this is really the only reason and referencing the 0 index is not an
option for the specs (maybe because in other languages than JavaScript
calling the first item from an empty list gives an error? I just don't
know) then I'd prefer an optional extra argument.
