**Incorrect (sequential execution, 3 round trips):**
const user = await fetchUser() const posts = await fetchPosts() const comments = await fetchComments()
**Correct (parallel execution, 1 round trip):**
const [user, posts, comments] = await Promise.all([ fetchUser(), fetchPosts(), fetchComments() ])
