How to execute code that comes after alert() when user finished interacting with alert box?

The alert method blocks execution until the user closes it:

alert('Some message');
alert('doing something else after the first alert is closed by the user');

use the confirm function:

if (confirm('Some message')) {
    alert('Thanks for confirming');
} else {
    alert('Why did you press cancel? You should have confirmed');
}
