Go Getting Started

To get started with Go programming, you'll need to follow these basic steps:

  1. Install Go: You can download and install the latest version of Go from the official website at https://golang.org/dl/. Follow the installation instructions for your operating system.

  2. Set up your Go workspace: A Go workspace is a directory where you keep your Go code and related files. By default, Go looks for a workspace in a directory called "go" in your home directory. You can create this directory if it doesn't already exist, or choose a different location by setting the GOPATH environment variable.

  3. Create a new Go module: A Go module is a collection of related Go packages that can be versioned together. To create a new module, create a directory for your project and run the command "go mod init <module_name>".

  4. Write your first Go program: Create a new file with a ".go" extension and write some Go code. For example, you could create a file called "hello.go" and write the following code:

package main

import "fmt"

func main() {
    fmt.Println("Hello, world!")
}

This program simply prints the message "Hello, world!" to the console.

  1. Build and run your program: To build your program, run the command "go build" in the directory where your source code is located. This will create an executable file that you can run. Alternatively, you can run the command "go run <filename>" to compile and run your program in one step.

Congratulations, you've just written and run your first Go program! From here, you can continue to explore the Go language and its features, including concurrency, error handling, and more.
