Whether you’re completely new to coding or switching from another language, this beginner’s tutorial will show you how to install Go, write your first program, and understand key concepts step by step.
Why Learn Go?
Go is widely used for developing backend services, cloud-native tools, command-line apps, and more. Here’s why developers love it:
- Simple syntax that’s easy to read and write
- High performance with fast compile times and execution
- Excellent tooling like
go build
,go test
, andgo fmt
Step 2: Create Your First Go Program
Let’s write and run a simple “Hello, World!” application:
- Create a folder for your project:
mkdir hello cd hello
- Initialize a Go module:
go mod init example.com/hello
- Create a new file named
hello.go
and add the following code:
package main import "fmt" func main() { fmt.Println("Hello, World!") }
- Run the program with:
go run hello.go
You should see: Hello, World!

fmt.Println(i)
}
Functions
func add(x int, y int) int { return x + y }
Step 4: Use Go’s Built-in Tools
Go comes with powerful commands that streamline development:
