## Promise.all() for Independent Operations
|
||
|
||
When async operations have no interdependencies, execute them concurrently using `Promise.all()`.
|
||
|
||
**Incorrect (sequential execution, 3 round trips):**
|
||
|
||
```typescript
|
||
const user = await fetchUser();
|
||
const posts = await fetchPosts();
|
||
const comments = await fetchComments();
|
||
```
|
||
|
||
**Correct (parallel execution, 1 round trip):**
|
||
|
||
```typescript
|
||
const [user, posts, comments] = await Promise.all([fetchUser(), fetchPosts(), fetchComments()]);
|
||
```
