eslint/no-unused-labels Correctness

✅ This rule is turned on by default.

🛠️ An auto-fix is available for this rule.

What it does

Disallow unused labels

Why is this bad?

Labels that are declared and not used anywhere in the code are most likely an error due to incomplete refactoring.

Example

OUTER_LOOP: for (const student of students) {
  if (checkScores(student.scores)) {
    continue;
  }
  doSomething(student);
}
