Go

Go is especially useful for backend services and infrastructure where predictable concurrency, explicit errors, and simple deployment matter.

Topics

• Bounded concurrency and cancellation — a tested worker-pool implementation using goroutines, channels, context.Context, and cooperative cancellation.

Learning path

1. Values, pointers, structs, methods, interfaces, and error handling.
2. Packages, modules, testing, benchmarks, and profiling.
3. Goroutines, channels, synchronization, and cancellation.
4. HTTP services, middleware, database access, and graceful shutdown.
5. Performance analysis, race detection, and production operations.
