## Hoist Static JSX Elements

Extract static JSX outside components to avoid re-creation.

**Incorrect (recreates element every render):**

```tsx
function LoadingSkeleton() {
  return <div className="h-20 animate-pulse bg-gray-200" />
}

function Container() {
  return <div>{loading && <LoadingSkeleton />}</div>
}
```

**Correct (reuses same element):**

```tsx
const loadingSkeleton = <div className="h-20 animate-pulse bg-gray-200" />

function Container() {
  return <div>{loading && loadingSkeleton}</div>
}
```

This is especially helpful for large and static SVG nodes, which can be expensive to recreate on every render.

**Note:** If your project has [React Compiler](https://react.dev/learn/react-compiler) enabled, the compiler automatically hoists static JSX elements and optimizes component re-renders, making manual hoisting unnecessary.
