What is Go?
Go (Golang) is a compiled language created at Google in 2009. It's designed for simplicity, fast compilation, and built-in concurrency — perfect for cloud infrastructure.
Why Go?
Go compiles to a single static binary, has a garbage collector with a tiny footprint, and its goroutines make concurrency trivial. It's the language of Docker, Kubernetes, and Terraform.
