### Only Call Hooks at the Top Level

**Don't call Hooks inside loops, conditions, or nested functions.** Instead, always use Hooks at the top level of your React function. By following this rule, you ensure that Hooks are called in the same order each time a component renders. That's what allows React to correctly preserve the state of Hooks between multiple `useState` and `useEffect` calls. (If you're curious, we'll explain this in depth [below](#explanation).)
