Get Component Script Error

Hello I am a Beginner at unity and I am having some trouble with errors

I am trying to create a jump scare but 4 errors come up and it has something to do with Get Component and I don’t know how to fix it (The Code is in JavaScript)

My Code:

var scare : GameObject;
var played = false;
var trig = false;

var scareSound: AudioClip;
////////Make sure its not visable and reset////////
function Start () {
	trig = false;
	scare.renderer.enabled = false;
	}
/////When player enters trigger/////// set to true///////
function OnTriggerEnter (other : Collider) {
	trig = true;
}
//////Enable renderer and trigger sound and timer/////
function Update () {
	if (trig == true) {
		scare.renderer.enabled = true;
		removeovertime ();
		makehimscream ();
	}
}
//// timer ////
function removeovertime () {
	yield WaitForSeconds (0.8);
	scare.renderer.enabled = false;
	Destroy(this.gameObject);
	
}
//// sound /////
function makehimscream () {
	if (!played) {
		played = true;
		audio.PlayOneShot(scareSound);
	}
}

Here Are My Errors:

Assets/Trig.js(9,15): BCE0144: ‘UnityEngine.GameObject.renderer’ is obsolete. Property renderer has been deprecated. Use GetComponent() instead. (UnityUpgradable)

AND

Assets/Trig.js(18,23): BCE0144: ‘UnityEngine.GameObject.renderer’ is obsolete. Property renderer has been deprecated. Use GetComponent() instead. (UnityUpgradable)

AND

Assets/Trig.js(26,15): BCE0144: ‘UnityEngine.GameObject.renderer’ is obsolete. Property renderer has been deprecated. Use GetComponent() instead. (UnityUpgradable)

AND

Assets/Trig.js(34,17): BCE0144: ‘UnityEngine.Component.audio’ is obsolete. Property audio has been deprecated. Use GetComponent() instead. (UnityUpgradable)

Please Help Me.

Thanks in advance

Those properties/members have been deprecated/marked as obsolete. The errors tell you what you need to do. GetComponent is needed to get the reference to the render an audio components that had a field/property in unity previously for ease of use.

modify your script as follows:

var scare : GameObject;
var played = false;
var trig = false;

var scareSound : AudioClip;
////////Make sure its not visable and reset////////
function Start() {
	trig = false;
	scare.GetComponent. < Renderer > ().enabled = false;
}
/////When player enters trigger/////// set to true///////
function OnTriggerEnter(other : Collider) {
	trig = true;
}
//////Enable renderer and trigger sound and timer/////
function Update() {
	if (trig == true) {
		scare.GetComponent. < Renderer > ().enabled = true;
		removeovertime();
		makehimscream();
	}
}
//// timer ////
function removeovertime() {
	yield WaitForSeconds(0.8);
	scare.GetComponent. < Renderer > ().enabled = false;
	Destroy(this.gameObject);

}
//// sound /////
function makehimscream() {
	if (!played) {
		played = true;
		GetComponent. < AudioSource > ().PlayOneShot(scareSound);
	}
}
