we don't yet have a javascript interface, however it should be possible to use eth console or geth console to connect to a running parity client
i haven't tried that yet, though...
Try geth --light console, available since v1.5.2, but listed under "Experimental Features". Syncs in minutes if not seconds.
Update - The initial sync took 11 minutes. Subsequently, syncing 7 hours worth of blocks took 8 seconds.
I'll document some light client stats below.
Here are some stats (the current block is 2972534:

Conclusion:
geth --lightseems a bit unstable currently for the retrieval of events from a historical part of the blockchain. The first retrieval of events from 1,000 blocks did not return the data in a reasonable time (I waited 7 minutes). I stoppedgethand restarted it and ran the same command again. The block data for the 1,000 blocks was already downloaded and the events were retrieved the second time in 15 seconds.- But the syncing and performance seems pretty good if you just need the current data.
Update
Syncing 7 hours worth of blocks took 8 seconds:
