js promise - good practice

promises.js

// bad
async function someAsyncFunc() {
    const user = await asyncGetUser();
    const categories = await asyncGetCategories();
    const mapping = await asyncMapUserWithCategory(user, categories);
}
 
// good
async function someAsyncFunc() {
    const [user, categories] = await Promise.all([
        asyncGetUser(),
        asyncGetCategories()
    ]);
    const mapping = await asyncMapUserWithCategory(user, categories);
}
