Uncaught ReferenceEror: nonExistentVariable is not defined


const CounterStike = () => {
  const [counter, setCounter] = useState(0);

  const incrementCounter = () => {
    setCounter(counter + 1);
  };

  // Introducing a bug: Referencing undefined variable
  console.log(nonExistentVariable);

  return (
    <div>
      <button onClick={incrementCounter}>Increment</button>
      <p>Counter: {counter}</p>
    </div>
  );
};

export default CounterStike

Getting this error: Uncaught ReferenceError: nonExistentVariable is not defined I have tried to resolve it by mine but nothing works

Solution

  • You need to remove the console.log(nonExistentVariable) line, as you have not defined this variable anywhere in your example.
