Let closure be FunctionCreate(Arrow, parameters, ConciseBody, scope, strict). + ... + + The non-normative note elaborates on the "scope" argument: + + An ArrowFunction does not define local bindings for arguments, super, this, or new.target. Any reference to arguments, super, or this within an ArrowFunction must resolve to a binding in a lexically enclosing environment. Typically this will be the Function Environment of an immediately enclosing function. Even though an ArrowFunction may contain references to super, the function object created in step 4 is not made into a method by performing MakeMethod. An ArrowFunction that references super is always contained within a non-ArrowFunction and the necessary state to implement super is accessible via the scope that is captured by the function object of the ArrowFunction. +---*/ + +var count = 0; + +class A { + constructor() { + count++; + } +} + +class B extends A { + constructor() { + (_ => super())(); + } +} + +var bar = new B(); + +assert.sameValue(count, 1); + +reportCompare(0, 0); |
