Javascript was the language I learnt with more or less. I think it's quite a good choice, but it is very easy to write "bad" Javascript, especially when it comes things like eval(). It seemed wonderful when I first discovered it, but not until some time later did I discover the kind of mess it can cause. I was also introduced to OO (of sorts) through JS... I perhaps wouldn't recommend this so much, it was incredibly confusing for me at first. I didn't have any real grounding in OO principles before I started though, so perhaps that would have helped.
