Fix docs for JS run, and add collect to docs about rethinkdb HOT 5 CLOSED

@ptrln -- this is by design, it's a way to use 'cursors' in node. If the callback returns true, it gets called again with the next record. If it returns nothing/false, it doesn't get called again (rethink assumes you don't want the rest of the records). An alternative is to call 'collect' instead of run, which will give you the whole dataset.

@wmrowan -- could you please improve the docs on this, and add 'collect' to the js docs?

@coffeemug , Thanks! I thought it might be something like that. Do you mean something like r.table('example').collect()? I tried running collect, and I got this error - TypeError: Object [object Function] has no method 'collect'

from rethinkdb.

Hmm, perhaps collect isn't exposed -- @wmrowan could you chime in?

Regardless, you'd need to pass collect a callback, which gets called with an array of documents.

ahh, checked the code, I believe it's query.run().collect(callback)

Renaming the issue -- this is a documentation problem.
