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 non-native JS class. Given the class
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 non-native, the presence of this node makes it instantiable,
and therefore reachable.
