Rails has JavascriptHelper but can you recommend other packages that  
make it easy for the Ruby programmer to create JavaScript on web pages?

I suggest you write native Javascript using jQuery - you’ll be glad you  
did. jQuery lets you work at the level of CSS selectors, e.g.

$(’.someclass’).hide(); // hide all elements with class someclass

The half-way house: install jRails and then the Rails helpers will  
output jQuery instead of Prototype.

The same with Prototype looks like this:

```
 $$('.someclass').invoke('hide');

```

jQuery is not as much better than Prototype as many people believe that  
just don’t know Prototype.

In the german JS-newsgroup the one and only answer to the question  
‘which JS-framework should I use?’ is ‘write your own. The existing ones  
are all bullshit’…

I can recommend Prototype as well.

Also, there’s this great talk by a person who KNOWS about JS:

(I know it’s an hour long, but I really took some lessons out of it. I  
think  
it’s worth the time investment)

and his great tool:

that helped me remove a lot of errors from my javascript stuff…

I like that one 😉

There are tons of frameworks out there, just pick one that has the kind  
of  
syntactic sugar you favor…  
Greetz!
