Spawn game objects on a timer

Question

I have this script that spawns enemies, but they only spawn once. So what I was wondering is if there is a way to add a timer or something into this script to make it so they will keep spawing. Here is the script.

 #pragma strict
  // Instantiates a prefab in a grid
  
  var prefab : GameObject;
  var gridX = 5;
  var gridY = 5;
  var spacing = 2.0;
  
  function Start () {
      for (var y = 0; y < gridY; y++) {
          for (var x=0;x<gridX;x++) {
              var pos = Vector3 (x, 0, y) * spacing;
              Instantiate(prefab, pos, Quaternion.identity);
          }
      }
  }

use InvokeRepeating , this will create every 2 seconds

  function Start () {
      float startIn=1;
      float every=2;
      InvokeRepeating("spawn", startIn, every);
   }
 
 spawn(){
       for (var y = 0; y < gridY; y++) {
           for (var x=0;x<gridX;x++) {
               var pos = Vector3 (x, 0, y) * spacing;
               Instantiate(prefab, pos, Quaternion.identity);
           }
        }
     }

var timer:float;

 function Update(){
 
 if (timer<0){Instantiate bad guys here; 
               timer=10;}
 
 
 timer=timer-Time.deltaTime;
 }

that should do it!
