✅ This rule is turned on by default. 🛠️ An auto-fix is available for this rule.

What it does

Checks for usage of the debugger statement

Why is this bad?

debugger statements do not affect functionality when a debugger isn't attached. They're most commonly an accidental debugging leftover.

Example

async function main() {
  const data = await getData();
  const result = complexCalculation(data);
  debugger;
}
