How to restart level when timer reaches 0?

I watched a tutorial in YouTube about creating a countdown timer. It works well. Problem is, the timer still keeps going even when it reaches 0.

How do I restart the scene when the timer hits 0?

HERE’S THE TUTORIAL I WATCHED: [Unity 4] Creating a simple countdown timer (JavaScript) - YouTube

EDIT : I mixed up c++, c# and java, change the first line to import UnityEngine.SceneManagement;

I copied the script from the video, just add 2 lines of code

#include UnityEngine.SceneManagement; //include this to use the SceneManager

function Update()
{
    timer -= Time.deltaTime;

    if(timer <= 0)
    {
        timer = 0;
        //You can restart the scene here
        SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
    }
}

What SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex); does is get the current scene and load it again, which simulates a ‘restart’ of the current scene
