I love Scala.js

it's amazing

Is Scala.js to Scala like ClojureScript to Clojure?

I know nothing about ClojureScript (and not much about Clojure).
Here's a tutorial sample:

package com.xxx
import org.scalajs.dom
import dom.document

import scala.scalajs.js.annotation.JSExport
import scala.scalajs.js.{Date, JSApp}

object XXXWebApp extends JSApp {
  def main(): Unit = {
    println("Hello XXX! " + new Date())

    appendPar(document.body, "Hello RXI! it is " + new Date())
  }

  @JSExport
  def addClickedMessage(): Unit = {
    appendPar(document.body, "You clicked the button at " + new Date())
  }

  def appendPar(targetNode: dom.Node, text: String): Unit = {
    val parNode = document.createElement("p")
    val textNode = document.createTextNode(text)
    parNode.appendChild(textNode)
    targetNode.appendChild(parNode)
  }
}

with HTML looking like this:

  <body>
    <script type="text/javascript" src="./target/scala-2.11/rxi-web-client-fastopt.js">
    <script type="text/javascript">
      const GOD = com.rxi.RxiWebApp()
      GOD.main();
    </script>
    <button id="click-me-button" type="button"
            onclick="GOD.addClickedMessage()">Click me!
  </body>

GWT 2.0?
