I'm following an online course and I'm certain that my code is exactly the same, but mine keeps running instead of stopping after 10 times. Can anyone see the problem?

for (let rep = 1; rep <= 10; rep = rep++) {
  console.log('Lifting weights repetition 1 ️‍♀️');
}

an assignment of a post increment does not change the assigned value. in short, you assign the same value. – Nina Scholz Jan 31 '22 at 18:28

Try this: `for (let rep = 1; rep <= 10; rep++)` – Jonathan.Brink Jan 31 '22 at 18:29

because `rep` is always equal to 1 – Ian Jan 31 '22 at 18:31

for (let rep = 1; rep <= 10; rep++) { console.log('Lifting weights repetition 1 ️‍♀️'); } the issue is caused at rep=rep++ – M. Twarog Jan 31 '22 at 18:31

To be precise, the order in which `rep = rep++` is executed is `rep = rep` and then `rep += 1`. The `rep + 1` in turn is never assigned to anything. – Webber Jan 31 '22 at 18:33
