case class LoadJSConstructor(cls: ClassType)(implicit pos: Position) extends Tree with Product with Serializable

Loads the constructor of a JS class (native or not).

cls must represent a non-trait JS class (native or not).

This is used typically to instantiate a JS class, and most importantly if it is a Scala.js-defined JS class. Given the class

@ScalaJSDefined
class Foo(x: Int) extends js.Object

The instantiation new Foo(1) would be represented as

JSNew(LoadJSConstructor(ClassType("Foo")), List(IntLiteral(1)))

This node is also useful to encode o.isInstanceOf[Foo]:

JSBinaryOp(instanceof, o, LoadJSConstructor(ClassType("Foo")))

If Foo is Scala.js-defined, the presence of this node makes it instantiable, and therefore reachable.
