Calling Hooks Conditionally Breaks React Rules and Causes Errors

I conditionally call a hook inside an if statement, expecting it not to run when condition fails. But React throws errors about hook order.

React expects hooks to execute in the same order every render. Conditional hook calls break this invariant and lead to runtime errors ([turn0search0]turn0reddit13]). Fix: jsx Copy code // ❌ Bad: if (isLive) { useHookA(); } else { useHookB(); }

// ✅ Good: const result = isLive ? useHookA() : useHookB(); Ensure unconditional hook invocation and consistent ordering across renders.
