Do something when a for loop ends

Question

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!');
    }
}

Answer 1

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

alert('Loop ended!');
