Accessing GetComponent() without instantiating

I am new to Unity Game Development and I find the following usage in code a bit confusing.

private Transform enemy;

// Start is called before the first frame update
void Start()
{
    enemy = GetComponent<Transform>();
}

According to the documentation GetComponent() is a public function. So how can this be accessed without being instantiated? I found a similar question was asked on Unity's community but I didn't find any of the answers answering the question exactly to the point. Please help me in understanding this. The link to question on Unity forum is below. Question

My Unity version is 2018.4.16f1 Thanks!

Your class most probably inherits from MonoBehaviour which inherits from Behaviour which inherits from Component.

Component implements GetComponent

Fazit: The instance which you are calling this method on is no other than this, the instance Start is called on.

Btw for Transform there is already a dedicated property Component.transform so you should not use GetComponent for getting a Transform reference.

you are calling the GetComponent() method of the GameObject you added your MonoBehavior to and assign it to the Transform enemy. It is even the first Answer from your linked Question.
