Advanced Async/Await in JavaScript: Boost Performance & Error Handling

Welcome back to MarkoCodeAcademy! In this action-packed video, we'll take your JavaScript skills to the next level by diving deep into advanced async/await techniques. You'll learn how to optimize performance, handle multiple asynchronous operations efficiently, and manage errors like a pro. We'll walk through a real-world example by building a simple weather app that pings multiple API endpoints, demonstrating both parallel and sequential execution of asynchronous tasks. Along the way, you'll discover the power of Promise.all and Promise.allSettled to supercharge your code's performance while ensuring robust error handling.
