Go (Golang) Online Compiler — Concurrent, Fast, Simple

Go is a statically typed, compiled language designed at Google by Rob Pike, Ken Thompson, and Robert Griesemer. It compiles in seconds, executes fast, and has first-class concurrency through goroutines and channels.

Go powers Docker, Kubernetes, Terraform, Prometheus, and thousands of microservices at Google, Cloudflare, Uber, and Dropbox. Its simple syntax and explicit error handling make it ideal for backend APIs, DevOps tools, and cloud infrastructure.

Example package main import "fmt" func fib(n int) int { if n <= 1 { return n } return fib(n-1) + fib(n-2) } func main() { for i := 0; i < 10; i++ { fmt.Printf("fib(%d) = %d\n", i, fib(i)) } }
