I always thought there was a better way to access the dom. This is a tool that allows you to use extremely simple syntax to access dom elements. It makes an object with the name of your choice (I chose "$") that contains a reference to all elements that have an id.
example:
<script> $.foo.innerHTML = "Hello world" </script>
You can even choose to use an object that already exists (I chose "document" because it makes sense)
document.foo.innerHTML = "Hello world"
If you want to live dangerously, you can even make everything global!
foo.innerHTML = "Hello world"
If not called/applied in another context, this will be window anyway. And I don't like document.all, because it erratically mixes IDs, names and classnames. The W3C DOM methods are much more straightforward (and with the new querySelector[All], they are really versatile).
