calling a function multiple times

hi guys i have been trying to finish space shooter tutorial but i got stuck at this part where i need to spawn waves i don’t what to do to make the following function starts a decent number of asteroids and keeps on going on its own :

function SpawnWaves () {
while (true) {
 yield WaitForSeconds (2);
 
    var spawnPosition : Vector3= new Vector3 (Random.Range (-spawnValues.x, spawnValues.x), spawnValues.y, spawnValues.z);
    var spawnRotation : Quaternion= Quaternion.identity;
    Instantiate (hazard, spawnPosition, spawnRotation);
}

What you want is something like this

function SpawnWaves () {
    // set up the initial spawn, I have 5, but you can change this
    for(var i : int = 0; i < 5; i++) {
        SpawnOneWave();
    }
    while (true) {
        yield WaitForSeconds (2);
        SpawnOneWave();
    }
}    

function SpawnOne Wave () {
    var spawnPosition : Vector3= new Vector3 (Random.Range (-spawnValues.x, spawnValues.x), spawnValues.y, spawnValues.z);
    var spawnRotation : Quaternion= Quaternion.identity;
    Instantiate (hazard, spawnPosition, spawnRotation);
}
