Safe Go Concurrency Patterns for Beginners

Concurrency in Go is easy to start, but misuse can cause race conditions that are hard to trace.

Key Points

• Start with a worker pool: a fixed number of goroutines reading tasks from a single channel.
• Prefer sharing data through channels, and use a mutex only to protect structures that really are shared.
• Use context to cancel work and avoid goroutines that hang with no time limit.
• Run tests with the race detector so race conditions are caught before release.

A simple pattern the whole team understands is worth more than a clever concurrency design.
