How to find a GameObject by name in Unity?

How to find GameObject by Name in Unity If we know the name of the GameObject in the scene we want to access we can use that information to find the reference in our Script.

What happens if no GameObject with name is found?

If no GameObject with name can be found, null is returned. If name contains a ‘/’ character, it traverses the hierarchy like a path name. For performance reasons, it is recommended to not use this function every frame. Instead, cache the result in a member variable at startup. or use GameObject.FindWithTag.
