Example migration:

import org.scalajs.dom

// Before (deprecated)
val response = dom.experimental.ResponseInit(myStatus, myStatusText, myHeaders)

// After
val response = new dom.ResponseInit {
  status = myStatus
  statusText = myStatusText
  headers = myHeaders
}

Note: this example has been updated to reflect corrections made in v2.1.0. For discussion see #624.

org.scalajs.dom.NodeList now takes a type parameter – I believe Node can be used in most of the cases: NodeList[Node]

JS-native traits that don't have their vars implemented should be initialized as noted above:

val response = new dom.ResponseInit {
  var status = myStatus
  var statusText = myStatusText
  var headers = myHeaders
}

There are traits that have the vars initialized. For example, MutationObserverInit is defined like this:

trait MutationObserverInit extends js.Object {
  var childList: js.UndefOr[Boolean] = js.undefined
  // ...

These are intended to be initialized the following way:

new MutationObserverInit {
  this.childList = someChildList
}

Note that we're not overriding the var in this case, rather we're imperatively re-assigning it in the constructor.

(thanks, Sébastien, for pointing this out!) (see #624)

There used to be a package object org.scalajs.dom.ext in 1.x providing strokePath , where did it go? A full-text search for strokePath in the main branch yields 0 results, was it removed?
