Does modern JavaScript have a terse way to get an object's property and raise an exception if that property doesn't exist?

Have you ever tried Rust? *ducks*

I'd be very interested in using it if there were a thing I could install that comes with a binary where I type a single command a directory of .rs turns into a single .js, but we're very far from that and I doubt we'll ever actually see it.

By what definition of .js?
