Being more pedantic, turboprops use gas turbine engines to power the propeller. "Jet engine" is incorrect when referring to gas turbine engine other than turbojets, such as turboprops, turbofans and turboshafts. Turbojets were the first variant of gas turbine engine to be put into use so "jet engine" ended up being used as a common term. Modern "jet planes" often use turbofans for their greater efficiency at similar performance levels, but "fan plane" sounds silly. The M1 Abrams uses a turboshaft engine but I've never heard it called a "jet tank" (which sounds badass).
