Change a sprite during the game- JS

I’m trying to swipe the enemy sprite, after his death. There’s a code which does this in the Unity tutorial, but my entire code is in Javascript. I tried to do the same thing but is not working, and I don’t know why… How do I fix this?

function Death(){
//gets the Sprite renderer of my enemy
ren = GameObject.Find(this.name).GetComponent(SpriteRenderer);
	
var renderers = GetComponentsInChildren(SpriteRenderer);
//desables all the other past sprites
	for(var s : SpriteRenderer in renderes){
		s.enabled = false;
	}
//and then enables a new one
	ren.sprite = DeadSprite;
	ren.enabled = true;
	}

Unity is not is not changing the Sprite at all…

Maybe, this will help?

var image : Sprite;

function Start () {
GetComponent(SpriteRenderer).sprite = image;
}
