The jet in jet-engine refers to the fact it uses jet propulsion - i.e. producing movement in one direction by ejecting a fluid in the opposite direction. This means that lots of things are actually jet engines - rocket engines and water jets being two common ones.

The propulsion of a 'jet engine' is normally through a gas turbine, which is a type of internal combustion engine, so you wouldn't get an electric gas turbine.

Replacing the gas turbine with an electric motor would in this case produce an electric jet engine.
