Run a script every 2 seconds

Unity Engine
1

I have a script which has to be executed every 2 seconds. Is there any way to do it on Unity itself or do I have to use a timer inside the script? If I have to use a timer on the script, could please post an example to use Timer?

using UnityEngine;

class Foo : MonoBehaviour {
    void Start () {
        // Do you stuff
        Invoke ("Start", 2);
    }
}

There are many other ways using IEnumerators or checking for a timer float in update etc. This is the easiest way.
