javascript - Leave a loop after 2 seonds

Question

I would like to repeat a text for 2 seconds in a while loop. How do I break the loop after 2 seconds?

This is what I have tried so far but it doesn't work:

var repeat = true;
setTimeout(function() { var repeat = false }, 2000)
while(repeat) {
    console.log("Let's repeat for 2 seconds...");
}

Answer 1

Additionaly to the other answer you could just check the time instead:

 const start = +new Date;

  while(+new Date < start + 2000) {
     console.log("Let's repeat for 2 seconds...");
 }
