what's wrong with this??

hi there, im converting a script from C# to javascript.

the problem here is there is an error stated : BCE0020 : An instance of type 'UnityEngine.Component is required to access non static member 'GetComponent'.

any help is appreciated.. ^___^

here are the scripts.

JAVASCRIPT

 #pragma strict

 var camera : GameObject;
 var menu : GameObject;
 var SelectSound : AudioClip;
 var SelectDownSound  : AudioClip;
 
 function Start(){
     camera = GameObject.Find("Main Camera");
     menu = GameObject.Find("Menu");
 }
 
 function OnMouseEnter(){
     audio.clip = SelectSound;
     audio.Play();
 }
 
 function OnMouseOver(){
     renderer.material.color = Color.blue;
 }
 
 function OnMouseExit(){
     renderer.material.color = Color.white;
 }
 
 function OnMouseDown(){
     audio.clip = SelectDownSound;
     audio.Play();
     
     RotateCamera();
 }
 
 function RotateCamera(){
 
     Camera.GetComponent(SmoothLookAtJS).target = menu.transform;// error in JS
 }
 
 
 

C# SCRIPT

 using UnityEngine;
 using System.Collections;
 
 public class BackToMenu : MonoBehaviour 
 {
     public GameObject camera;
     public GameObject menu;
     public AudioClip SelectSound;
     public AudioClip SelectDownSound;
     
     void Start()
     {
         camera = GameObject.Find("Main Camera");
         menu = GameObject.Find("Menu");
     }
     
     void OnMouseEnter() 
     {
         audio.clip = SelectSound;
         audio.Play(); 
     }
     
     void OnMouseOver() 
     {
         renderer.material.color = Color.blue;
     }
     void OnMouseExit() 
     {
         renderer.material.color = Color.white;
     }
     void OnMouseDown() 
     {
         audio.clip = SelectDownSound;
         audio.Play();
         
         RotateCamera();
     }
     
     void RotateCamera()
     {
     camera.GetComponent<SmoothLookAt>().target = menu.transform;// no error on C#
     }
 }
