> Use explicit ternary operators instead of && for conditional rendering. Apply when rendering values that could be 0, NaN, or other falsy values that might render unexpectedly. Use when this capability is needed.

## 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>
```
