hiding a mesh object temporarily

Unity Engine
1

I have been through the api without success trying to find out how to hide a mesh object or gameobjet

I can find it with tag or name but then how do I tell that it must hide until I unhide it?

I found
public class Something : MonoBehaviour
{
void Update()
{
//notice you don’t need to cast here.
ScriptName sn = gameObject.GetComponent()
sn.DoSomething();
sn.someVariable=5;
}
}
But where in the api is there described how to talk to the object to hide/unhide??

Disable the renderer.
