How to use sweetalert2 to Restart (JavaScript)

Question

Old code: restart(" Game Over. Try again!");

    playerLives = 10;
    playerLivesCount.textContent = playerLives;
    setTimeout(() => window.alert(text), 100);
};

This works great in a popup window. I need a pretty popup so i decided to use sweetalert2.

New code: Swal.fire(" Game Over. Try again!");

But now "OK" button does not run the function Restart.

How to use restart with Swal.fire ?

There's not enough context here. What is the restart function, and where does it come from? What was the original functionality? — micahlt, Jul 19 '22 at 19:07

Assuming that restart is a function that restarts the game, you could write the alert as follows:

Swal.fire(" Game Over. Try again!").then(() => {
  restart();
});

You would also want to remove the logic from the restart function that previously fired an alert.

it works. but there is still a popup with message "undefined". is it possible to get rid of it? – Denis Jul 19 '22 at 19:18
Where is the `restart` function defined? What does it do? – micahlt Jul 19 '22 at 19:18
I updated the question - added information about the function restart – Denis Jul 19 '22 at 19:24
So just remove the second to last line that says `setTimeout(() => window.alert(text), 100);`. – micahlt Jul 19 '22 at 19:25
