Looking for good resources for learning JavaScript

As the title says, seeking recommendations on JavaScript tutorials. I have some basic experience incorporating JavaScript into HTML, and am competent (though by no means a whiz) in MS Access. I’m pretty damned good with Excel, though. That’s kind of the extent of my programming experience, so that should give an idea as to where the skill level should be targeted.

I’m looking for books, but also for quality instructional software.

Have you seen the tutorial at w3schools? It may be beneath your skill level if you have some experience, but it’s worth a look.
