A Jet engine sucks in air, compresses it and forces it out the back to produce thrust.
A Rocket motor uses a chemical reaction of two substances in a sealed container to produce thrust. When the container is opened the chemicals force their way out.
Imagine a bottle of lemonade. Shake it up and the open the top. That is your rocket motor.

a jet engine sucks in air and then uses that to propel itself forward. the rocket engine releases gases from a chemical reaction through a small opening with a lot of pressure providing the rocket with thrust required to blast off! In short a jet engine doesnt work outside the atmosphere while rocket engine is self-sufficient

A Rocket engine is self propulsion that is the jet flow required for it's forward motion is generated from its own reactiopns. But a jet engine simply fans in the outer Air compresses and heatd it and jets it out

A jet engine requires an intake of air to operate. A rocket engine is "self-sufficient".

Rocket engines do not require an external air/oxygen supply as the fuel contains propelent and oxidiser. Thats why rockets work in space. With no external atmosphere. A jet engine would not be able to operate in space as it requires an external oxidiser ie thee atmosphere.

It is the difference between a nazi V1 and a V2.
The V1 was a simple ram jet without a turbine and compressor, relying on the airflow into the front opening and burning fuel in that air.
The V2 was a rocket combing two reactive liquids in a combustion chamber to produce thrust and achieving supersonic speed.
