Is it possible to combine two js.Dynamic objects

Say I have 

val obj1 = js.Dynamic.literal(attr1 = "x")
val obj2 = js.Dynamic.literal(attr2 = "y")

and I would like to combine obj1 and obj2 to yield and object of

{attr1 = "x", attr2 = "y"}

Does js.Dynamic have a method to yield such a combination?

I put the same question to the scala.js forums and was pointed to js.Object.assign

There is no existing method doing that. In ES6 there is Object.assign, but it is not supported in IE.

I recommend re-implementing it in Scala.js:

def mergeJSObjects(objs: js.Dynamic*): js.Dynamic = {
  val result = js.Dictionary.empty[Any]
  for (source <- objs) {
    for ((key, value) <- source.asInstanceOf[js.Dictionary[Any]])
      result(key) = value
  }
  result.asInstanceOf[js.Dynamic]
}

And now you can simply do

mergeJSObjects(obj1, obj2)
