Which nations fielded jet fighters during wwii?

Just about every airplane flown by any nation in World War II was a propeller-driven plane. The Germans fielded the first operational jet fighter, the Messerschmitt Me 262, but it only saw partial action in World War II because it was transported late in the war and underwent from some engine issues. Here were other jet aircraft before the Me-262, but it was the first one to be delivered to the troops and used in combat operations. The first jet aircraft was the German HE 178, followed by Italian and British jets (N1 and Gloster E. 28 respectively).
