## Use Explicit Conditional Rendering
|
|
|
|
Use explicit ternary operators (`? :`) instead of `&&` for conditional rendering when the condition can be `0`, `NaN`, or other falsy values that render.

**Incorrect (renders "0" when count is 0):**
|
|
|
|
```tsx
|
|
function Badge({ count }: { count: number }) {
|
|
return <div>{count && <span className="badge">{count}</span>}</div>;
|
|
}
|
|
|
|
// When count = 0, renders: <div>0</div>
|
|
// When count = 5, renders: <div><span class="badge">5</span></div>
|
|
```
|
|
|
|
**Correct (renders nothing when count is 0):**
|
|
|
|
```tsx
|
|
function Badge({ count }: { count: number }) {
|
|
return <div>{count > 0 ? <span className="badge">{count}</span> : null}</div>;
|
|
}
|
|
|
|
// When count = 0, renders: <div></div>
|
|
// When count = 5, renders: <div><span class="badge">5</span></div>
|
|
```
