javascript - Do something when a for loop ends

I have a for loop in JavaScript, and I want some code to run when it ends. This works, but I'm wondering if there are any simpler solutions:

for (var i = 1; i <= 100; i++) {
    console.log('Line ' + i);

    if (i === 100) {
        alert('Loop ended!');
    }
}

Sorted by: Reset to default 17

for (var i = 1; i <= 100; i++) {
    console.log('Line ' + i);
}

alert('Loop ended!');

unless I'm missing something, what's wrong with:

for (var i = 1; i <= 100; i++) {
    console.log('Line ' + i);
}

alert('Loop ended!');

why dont you do like this?

Array.from(Array(100), (_, i) => console.log('Line ' + (i + 1)));
alert('Loop ended!');

Try this

for (var i = 1; i <= 100; i++) {
   console.log('Line ' + i);
}

alert('');
