loops - Print to console values between to integers infinitely in JavaScript

I would like to console.log values between 1 and 5 infinitely with a small delay of few seconds using JavaScript. I am trying to run the following code, but it stops after printing 1.

    var z = 0
    setTimeout(function() { 
      if (z==6) {z=0};
        z+=1;
        console.log(z);

    }, 2000);

Is it possible to implement this using setTimeout function?

Answer

You are looking for setInterval:

var z=0; 
setInterval(function() { 
  if (z==6) {z=0};
  z+=1;
  console.log(z);
}, 2000);
