English:

When I see them come, I know they could never compete
JavaScript is taking over all the streets
Runs on machines and runs in the ether
This is how we roll and this is how we see it
This is superka, I tell them never slow down
Like stream events from a virtual dom
Push the web forward till kingdom come
Ultimately native apps have to succumb
Legion! You better figure this!
The best people are here, JSConf is the wickedest
Keep a close distance, this is love like Winnie and Tigga
Bust open the ceiling like "bigger-ness"
JS rules like Agent Lexie
Check on the Internet we are the new sexy
This is not a German cartoon like Fix and Foxie
This is the realest thing this is no proxy
JSConf is the bomb
From far an wide people come
Code run, and the community bonds
We invite the world to find out how we rooooolll
