Hello @MFlyer!

Thanks for opening an issue about this - It's a fair point, Reflect is not part of the ES5 spec.

I guess we could substitute this for delete (although that keyword feels kinda weird to use), or use a shim (which inherently would do the same).

@asgvard: What do you think?

Hi @predikament & @asgvard , my suggestion: I had a local git clone and used babel with corejs instead of the ts-loader -> targeting something not having ES5 support (e.g. a chrome 38) will grant you a full es5 compliant index.js - tested working (on a real tv device using an old Chrome 47)
