    ...items, the "spread" operator of ECMAScript 6.

    It is only valid in the args/items of a JSNew, JSFunctionApply, JSDotMethodApply, JSBracketMethodApply, or JSArrayConstr.

    items

    An Array whose items will be spread (not an arbitrary iterable)

  41. case class JSSuperBracketCall(cls: ClassType, receiver: Tree, method: Tree, args: List[Tree])(implicit pos: Position) extends Tree with Product with Serializable

    Calls a method inherited from the parent class of cls on receiver.

    Calls a method inherited from the parent class of cls on receiver.

    cls must be a Scala.js-defined JS class.

    Given the Scala.js-defined JS class

    @ScalaJSDefined
    class Foo extends Bar

    The node

    JSSuperBrackerCall(ClassType(Foo), receiver, method, args)

    which is printed as

    receiver.Foo::super[method](...args)

    has the following semantics:

    Bar.prototype[method].call(receiver, ...args)

    If this happens to be located in an instance method of Foo, *and* receiver happens to be This(), this is equivalent to the ES6 statement

    super[method](...args)
  42. case class JSSuperBracketSelect(cls: ClassType, receiver: Tree, item: Tree)(implicit pos: Position) extends Tree with Product with Serializable

    Selects a property inherited from the parent class of cls on receiver.

    Selects a property inherited from the parent class of cls on receiver.

    cls must be a Scala.js-defined JS class.

    Given the Scala.js-defined JS class

    @ScalaJSDefined
    class Foo extends Bar

    The node

    JSSuperBrackerSelect(ClassType(Foo), qualifier, item)

    which is printed as

    qualifier.Foo::super[item]

    has the semantics of an ES6 super reference

    super[item]

    as if it were in an instance method of Foo with qualifier as the this value.

  43. case class JSSuperConstructorCall(args: List[Tree])(implicit pos: Position) extends Tree with Product with Serializable

    Super constructor call in the constructor of a Scala.js-defined JS class.

    Super constructor call in the constructor of a Scala.js-defined JS class.

    Exactly one such node must appear in the constructor of a Scala.js-defined JS class, at the top-level (possibly as a direct child of a top-level Block). Any other use of this node is invalid.

    Statements before this node, as well as the args, cannot contain any This() node. Statements after this node can use This().

    After the execution of this node, it is guaranteed that all fields declared in the current class have been created and initialized. Up to that point, accessing any field declared in this class (e.g., through an overridden method called from the super constructor) is undefined behavior.

    All in all, the shape of a constructor is therefore:

    {
      statementsNotUsingThis();
      JSSuperConstructorCall(...argsNotUsingThis);
      statementsThatMayUseThis()
    }

    which currently translates to something of the following shape:

    {
      statementsNotUsingThis();
      super(...argsNotUsingThis);
      this.privateField1 = 0;
      this["publicField2"] = false;
      statementsThatMayUseThis()
    }
  44. case class JSUnaryOp(op: Code, lhs: Tree)(implicit pos: Position) extends Tree with Product with Serializable

    Unary operation (always preserves pureness).

    Unary operation (always preserves pureness).

    Operations which do not preserve pureness are not allowed in this tree. These are notably ++ and --

  45. case class Labeled(label: Ident, tpe: Type, body: Tree)(implicit pos: Position) extends Tree with Product with Serializable

  46. sealed trait Literal extends Tree

    Marker for literals.

    Marker for literals. Literals are always pure.

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

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

    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.

  48. case class LoadJSModule(cls: ClassType)(implicit pos: Position) extends Tree with Product with Serializable

    Like LoadModule but for a JS module class.

  49. case class LoadModule(cls: ClassType)(implicit pos: Position) extends Tree with Product with Serializable

  51. case class Match(selector: Tree, cases: List[(List[Literal], Tree)], default: Tree)(tpe: Type)(implicit pos: Position) extends Tree with Product with Serializable

    A break-free switch (without fallthrough behavior).

    A break-free switch (without fallthrough behavior). Unlike a JavaScript switch, it can be used in expression position. It supports alternatives explicitly (hence the List[Tree] in cases), whereas in a switch one would use the fallthrough behavior to implement alternatives. (This is not a pattern matching construct like in Scala.)

  53. case class ModuleExportDef(fullName: String)(implicit pos: Position) extends Tree with Product with Serializable

    AST node of the IR.

    A hash of a tree (usually a MethodDef).

    A hash of a tree (usually a MethodDef). Contains two SHA-1 hashes
