Mistake log: put code in the wrong place

I had to write code along the lines of the following. The code is not that important.

const afterState = [...state];
for (const [iSwitch,count] of Object.entries(switchCountBySwitch)) {
    for (const clock of SWITCHES[iSwitch]) {
        afterState[clock] = (afterState[clock] + 3 * count) % 12;
    }
}
const success = afterState.every(clock => clock === 0);
if (success) {
    currentMinCount = currentCount;
}

I made a mistake by putting a portion of the code inside the wrong scope.

const afterState = [...state];
for (const [iSwitch,count] of Object.entries(switchCountBySwitch)) {
    for (const clock of SWITCHES[iSwitch]) {
        afterState[clock] = (afterState[clock] + 3 * count) % 12;
    }
    const success = afterState.every(clock => clock === 0);
    if (success) {
        currentMinCount = currentCount;
    }
}

No wonder I got the wrong answer. I should make sure to read the code carefully (esp. when debuggers are not available)
