Key Strengths
Concurrency: Lightweight goroutines and channels simplify parallel workloads.
Fast Compilation: Rapid build cycles enable quick iteration and CI efficiency.
Static Binaries: Easy deployment—no complex runtime dependencies.
Standard Library: Rich, batteries-included ecosystem (HTTP, crypto, tooling).
Tooling: Built-in formatting (gofmt), vetting, profiling, race detection.
Cross-Compilation: Target multiple OS/arch with simple env flags.
Hello World
package main
import "fmt"
func main(){
fmt.Println("hello world")
}
Goroutines & Channels
package main
import (
"fmt"
"time"
)
func main(){
ch := make(chan string)
go func(){
time.Sleep(200 * time.Millisecond)
ch <- "done"
}()
fmt.Println("waiting...")
fmt.Println(<-ch)
}
Design Philosophy
Go removed many features (inheritance, generics at first, exceptions) to encourage clarity, predictable performance, and a uniform code style across teams.
When to Use It
Choose Go when you need high-performance network services, scalable APIs, build-time safety, and minimal runtime overhead.
