Huffy Savannah Cruise bike

Its a moderately modern version of a fairly traditional design.

The rear derailleur suggests its in the last 20 years, and the one-piece crank implies its a lower-cost variation.

The alloy wheel rims also show is relatively recent - a 1984 era bike would have had steel rims.

The zip ties holding cables to down and top tubes are a bit anachronistic, and the left/front brake cable is flapping in the breeze - I'd loosely secure that to the other cables in front of the headset.
Not sure if the handlebar has reflections or rust in the photo, could be either.

Looks like a loverly bike to me - as long as the moving bits move smoothly, and the brakes work reliably, then it should be an enjoyable ride for decades to come.
