what's with JavaScript community to make everything end in "js"? You don't see Ruby guys ending every one of their product names in "rb" or Python guys in "py".

The NumPy, Scrapy and SciPy folks may disagree :)

don't forget the web.py folks!

The java equivalent was '4j'. It's mildly useful on a mixed community like HN, you've got some idea before you click through what the target developer audience is.

Or worse, some incredibly eyeroll-worthy pun about coffee.

JavaScript is rather long. This can be an issue with domain names, event names, Twitter handles, etc. "Ruby" is a lot more succinct which is why we tend to use it as-is.

Same reason there are still plenty of Java projects out there that stick a "J" in the start of the name.

Maybe to avoid name collisions?
