That's funny because JavaScript could be considered a new language (unless you were counting the "JavaScript, HTML, CSS knowledge useful" descriptions). Languages take time, two Golang jobs is already pretty good given how young a language it is.
Its popularity increasing doesn't make it a new language. If you spend seconds on a web search you'll see that two is pathetic compared to elsewhere - I'm commenting on London there, not Go, or Elixir, both of which I would love to use, hence my grumbling.
JavaScript is not a good comparison. Say I didn't like JavaScript, I can't just start writing Python for the browser. I have a choice of either shipping a product or not. So many learn, know and use it because they have no choice.
