In, ES6. This is a breaking (hopefully nothing) change from ES5 that was suggested by Mark Miller.
The desire is to decrease the non-determinism that an early throw introduces. In the ES6 approach all property updates that can occur will occur, before the exception is thrown instead of leaving the object in a less well defined partially updated state.
