Apa iku Go lan kanggo apa dhisine dirancang?

Question

Accepted Answer

**Go** (Golang) yaiku basa sing type-static lan compiled sing digawe ing Google, dirancang kanggo **kesederhanaan, kompilasi cepet, lan concurrency sing wis dienggal**. Filosofine yaiku dadi cilik lan eksplisit — sawetara feature, gampang dibaca, produktif ing skala gedhé.

## Hello World sing cilik

```go
package main

import "fmt"

func main() {
    fmt.Println("Hello, World")
}
// `go run main.go` to run, or `go build` to make a single native binary
```

## Ciri-ciri kunci

```text
✓ Compiled to native code — fast execution, single static binary (easy deployment)
✓ Statically typed — type safety, errors caught at compile time
✓ FAST compilation — builds in seconds even for large projects
✓ Built-in concurrency — goroutines & channels as language primitives
✓ Garbage collected — automatic memory management
✓ Deliberately SIMPLE — small language spec, few keywords, one obvious way
✓ Great standard library + tooling (go fmt, go test, go mod built in)
```

## Model concurrency — fitur sing nggawe Go beda

```go
go doWork()         // launch a goroutine — a lightweight concurrent task
ch := make(chan int) // a channel for communicating between goroutines
```

Go nggawe concurrency dadi fitur kelas utama, gampang dianggo karo **goroutine** (thread sing abot banget — bisa jalankan jutaan) lan **channel** (kanggo komunikasi sing aman). Iki minangka alasan utama mengapa Go dipilih kanggo server lan sistem jaringan.

## Filosofi kesederhanaan

```text
Go deliberately OMITS features common elsewhere (no inheritance, no exceptions,
no generics until 1.18, minimal syntax) to keep code simple and uniform.
→ "Less is more": easy to read others' code, fast onboarding, consistent style.
```

## Go dianggo kanggo apa

```text
✓ Cloud infrastructure & DevOps — Docker, Kubernetes, Terraform are written in Go
✓ Backend APIs & microservices — fast, concurrent, easy to deploy
✓ CLI tools, network services, distributed systems
```

## Kenapa iki penting

Combination saka Go yaiku kesederhanaan, kompilasi cepet, performance native, deployment single-binary sing gampang, lan utamane **concurrency kelas utama** (goroutine/channel) nggawe Go dadi pilihan paling dhisik kanggo cloud infrastructure, backend service, lan DevOps tooling — akèh banget saka modern cloud stack (Docker, Kubernetes) ditulis nganggo Go.

Paham filosofi design-ne — kesederhanaan sing sengaja tinimbang kaayaan feature, eksplisitness tinimbang magic, concurrency sing wis dienggal sa basa — njelasake mengapa kode Go katon lan kroso beda saka basa liya lan mengapa dheweke kuwat sa sistem scalable lan jaringan.

Fondasi iki ngerangka kabeh bab liya babagan kerja ing Go.
