Promise.all() for Independent Operations
When async operations have no interdependencies, execute them concurrently using Promise.all().
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()
])
