Go overview

Go (Golang) is a statically-typed, compiled language developed at Google, designed for simplicity, fast compilation, and built-in concurrency via goroutines and channels. Its garbage collector and single-binary output make it popular for cloud-native services and CLI tooling. Go is the language of Kubernetes, Docker, Terraform, Prometheus, and much of the CNCF ecosystem. The standard library is comprehensive enough that many services require few third-party dependencies. Common patterns include the context package for cancellation propagation, interfaces for dependency injection, and table-driven tests. Popular frameworks include Gin, Echo, Chi (HTTP routing), and gRPC-go for RPC services.
