go-concurrency-examples

A hands-on collection of Go concurrency examples.
This repository contains small, self-contained programs that demonstrate Go’s concurrency primitives — goroutines, channels, synchronization, timeouts, and more.

---

🚀 Features

• Simple, focused examples of Go concurrency
• Covers goroutines, channels, select statements, timeouts, and sync primitives
• Easy to run and experiment with
• Useful as a reference or learning resource
