I spend about 30% of my time at work in Scala, I&#x27;m very familiar. I&#x27;m also familiar with Scala.js, though I don&#x27;t use it.<p>Normally you don&#x27;t need to clarify that Scala is interpreted to Java as that is the expected behaviour.<p>Scala and many other languages get compiled to javascript, but I think most people don&#x27;t expect that to say &#x27;Scala in your browser&#x27; or similar because that is not what is happening.<p>So in some ways your are proving my point by saying that Scala is not running on the Tessel.<p>But really, probably not worth all the effort either of us are putting into this. :)
