How i turn off the Emitter after few seconds?

Here's a simple script you can put on the object with the particle emitter:

function Start(){

    Invoke("StopEmitter", 3); //In 3 seconds, runs StopEmitter function

}    

function StopEmitter(){

    gameObject.GetComponent(ParticleEmitter).emit= false; //tell the emitter to stop.

}

I used coroutine to achieve the wait behavior. But i don’t is there any performance issue or its a bad approach for this secenario.

private ParticleSystem ps;

 private void method1(){
        StartCoroutine(nextLevelLoadTime());
 }

 IEnumerator startAndStopParticleSystem()
    {   
        ps = GetComponentInChildren<ParticleSystem>();
        ps.Play();
        yield return new WaitForSeconds(3);
        ps = GetComponentInChildren<ParticleSystem>();
        ps.Stop();
        yield return new WaitForSeconds(1);
        callOtherFunction
    }
