Asynchronous JavaScript

Summary

Promises and async/await — the patterns you'll use constantly to fetch data from your backend, query a database, or wait on any operation that doesn't complete instantly.

• 1Fetch data from an API using both `.then()` chains and async/await, and compare readability.
• 2Practice `Promise.all()` to run multiple independent requests in parallel.
• 3Learn to handle errors correctly with `try`/`catch` around `await`.
