Go is more likely to replace Java as high throughput/low latency server technology.

I've seen it in huge companies working with lots of data at high speeds.

Javascript sees a lot of use in small shops where devs only want to learn a few languages, or for fullstack devs who work on both ends of the stack.

You see it a lot in HN because javascript is getting pretty saturated - people are already doing EVERYTHING in it. Go on the other hand is just breaking into a few key areas, and is a lot younger, and I would even go as far as to say more exciting.
