In this video, we are going to explore how to create a toy implementation of Async/Await in Go. If you want to learn something about Trace Flight Recording in Go, feel free to check out this video: • The new Trace Flight Recorder in Go 1.25 i...
📝 Description
Ever wanted JavaScript or C#-style Async/Await in Go? In this video, we'll build a custom Future type using Go generics that brings familiar async programming patterns to Go's concurrent world. We'll explore how to implement this pattern from scratch, and learn some important concurrency concepts along the way. It's important, though, that this video is only for educational reasons and should NOT be used in production. You'll learn the following things:
• What Future types are and how they differ from channels
• How to implement Async/Await patterns using Go generics and concurrency features
• Advanced error handling with panic recovery
• Practical concurrency patterns with goroutines and channels
