Async/await has fundamentally changed how we write asynchronous JavaScript. Instead of chaining .then() calls, we can now write code that reads top-to-bottom while still remaining non-blocking.
Start with Promise.all
When you have independent operations, always reach for Promise.all before writing sequential awaits. It reduces total latency to the slowest operation instead of the sum of all operations.
const [users, posts] = await Promise.all([fetchUsers(),fetchPosts(),]);Handle errors with try/catch
Wrap awaited calls in try/catch blocks and translate raw errors into meaningful, typed failures that your UI can react to.
Remember: async functions always return a Promise. Returning a value is equivalent to resolving, and throwing is equivalent to rejecting.
