Converting C# to JS: rendering a mesh

So this is what I have:

GetComponent(MeshRenderer).enabled = false;

I got this from another question, but the rest of my script is Java and I was wondering if anyone knows a way to do this in Java rather than c#

basically, I have a box of matches, which I collect and after I collect it, what's SUPPOSED to happen is a note pops up on the screen when I get near the fireplace, telling me to use my matches. I then press "e" and voila, a fire appears...

Here is my script:

 #pragma strict
 
 var buttonInRange;
 var buttonActivated;
 var batterySound : AudioClip;
 var Transparent : Material;
 
 var Matches : GameObject;
 var Fire : GameObject;
 
 private var hasPlayed = false;
 
 function Start ()
 {
 //THIS IS WHERE I NEED HELP
 GetComponent(MeshRenderer).enabled = false;
 }
 
 
 function OnTriggerEnter (c : Collider)
 {
     buttonInRange = true;
 
 }
 
 
 function OnTriggerExit (c : Collider)
 {
     buttonInRange = false;
 
 }
 
     if (buttonInRange == true)
         {
 
         if (Matches == false)
 
             {
              
             GUI.Label (Rect (Screen.width/2-50, Screen.height/2-55, 120, 50), "Use matches");
     
             }
         }
     }
 
 
 function Update ()
 {
     if (buttonInRange == true)
     {
         if (Input.GetKeyDown ("e"))
         {
             AudioSource.PlayClipAtPoint(batterySound, transform.position);
 //I ALSO NEED HELP HERE
             GetComponent(MeshRenderer).enabled = false;
 
             }
         }
         
     }
 
 

The problem I'm having is I can't make the fire start off invsible when the scene loads and become visible when I click "e" and have collected my matches.

If it helps, here is my match script:

 var buttonInRange;
 var buttonActivated;
 var batterySound : AudioClip;
 
 
 private var hasPlayed = false;
 
 function OnTriggerEnter (c : Collider)
 {
     buttonInRange = true;
 
 }
 function OnTriggerExit (c : Collider)
 {
     buttonInRange = false;
 
 }
 function OnGUI ()
 {
     if(buttonInRange == true)
     {
         GUI.Label (Rect (Screen.width/2-50, Screen.height/2-55, 120, 50), "Pick up matches");
     
     }
 
 }
 function Update ()
 {
     if (buttonInRange == true)
     {
         if (Input.GetKeyDown ("e"))
         {
             if(!hasPlayed)
             {
                 AudioSource.PlayClipAtPoint(batterySound, transform.position);
                 Destroy(gameObject);
                 hasPlayed = true;
             }
             }
         
         }
     
     }
 

Any help is much, much appreciated :D
