Where do you recommend an experienced developer learn Javascript?
<p>I'd like to learn some Javascript <strong>before</strong> jumping into a framework like jQuery or Moo Tools.</p>

<p>Since I'm already familiar with C#/Java/Python, I'd like a resource that just shows me how to do things and not waste time with, this is an object, here's how you add numbers, etc.</p>

<p>What resource would you recommend for me? Thank you very much.</p>
