Why This Happens

In React, hooks were called in a different order between renders. This is one of the most common React errors developers encounter. Understanding the root cause helps you fix it quickly and prevent it from recurring.

The Problem

function App({ show }) {
  if (!show) return null;
  const [x] = useState(0); // After return!
}

The Fix

function App({ show }) {
  const [x] = useState(0); // Before return!
  if (!show) return null;
}
