What is the point of "using UnityEngine.SceneManagement;" in our code?

In a lecture, we wrote using “UnityEngine.SceneManagement”, don’t we already use “using UnityEngine”?

Unity is modularised.

That means, not every piece of code is included in UnityEngine, some of it is loaded into other namespaces. The one for Loading and handling scenes is called UnityEngine.SceneManagenent.

Oh, thanks!
