## Hoist Static JSX Elements
|
|
|
|
Extract static JSX outside components to avoid re-creation.
|
|
|
|
**Incorrect (recreates element every render):**
|
|
|
|
```tsx
|
|
function LoadingSkeleton() {
|
|
return <div className="animate-pulse h-20 bg-gray-200" />
|
|
}
|
|
|
|
function Container() {
|
|
return (
|
|
<div>
|
|
{loading && <LoadingSkeleton />}
|
|
</div>
|
|
)
|
|
}
|
|
```
|
|
|
|
**Correct (reuses same element):**
|
|
|
|
```tsx
|
|
const loadingSkeleton = (
|
|
<div className="animate-pulse h-20 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.
