If it's helpful, you can look at how newless handles this: https://github.com/mr0grog/newless/
It's a little more complicated than the earlier replies because many implementations have classes but not `Reflect.construct`, but it goes gracefully allow ES5- function-style constructors to inherit from class-style constructors. At the end of the day, the one restriction you can't really work around is not being able to touch `this` inside the constructor before calling the super class’s constructor (unless you don't call it at all, though that will no longer work if/when you transition to proper classes). -Rob On May 13, 2016, at 6:35 PM, Renki Ivanko <[email protected]> wrote: >> That said, can't the right thing be done using Reflect.construct? > > It can: > > ```js > function B() { > return Reflect.construct(A, arguments) > } > ``` > > `instanceof B` will be `false`, though. > _______________________________________________ > es-discuss mailing list > [email protected] > https://mail.mozilla.org/listinfo/es-discuss
