#61 Golang - Mastering Concurrency: Handling Errors with errgroup

In this video, we dive deep into handling concurrency in Go using the powerful errgroup. You’ll learn how to manage multiple goroutines, handle errors effectively, and implement context-based cancellations across concurrent tasks.  We’ll walk through a real-world example, building a simple web scraper to fetch multiple URLs concurrently and demonstrate how to handle errors and limit the number of simultaneous requests to prevent overload. Using Go’s errgroup package, you’ll see how easy it is to group tasks, capture errors, and control cancellations all in one place. Whether you’re developing APIs, handling database queries, or building parallel processing pipelines, this technique can improve the reliability and efficiency of your Go applications.
