One of Go’s most powerful features is its built-in support for lightweight concurrency through goroutines and channels. This course takes you step by step from theory to production-ready concurrency. You’ll begin by understanding what goroutines are, how they differ from OS threads, and how Go achieves such efficient parallel execution. Next, you’ll master the use of channels—Go’s unique mechanism for communicating safely between goroutines—learning unbuffered, buffered, and directional channels along with the select statement for multiplexing.
To make the concepts stick, we guide you through practical concurrency patterns like worker pools, fan-in/fan-out, rate limiting, timeouts, and graceful shutdowns with the context package. You’ll see how to avoid common pitfalls such as race conditions, deadlocks, and memory leaks, while developing a mindset for writing reliable concurrent code. By the end, you’ll have hands-on experience building systems like a web scraper, a concurrent task scheduler, and a log processor—proving you can confidently harness Go’s concurrency model for real-world projects.
