How to start golang

The Go language (also known as Golang) is a powerful programming language widely praised by developers for its simplicity, efficiency, and concurrency. If you are interested in Golang, this article will teach you how to get started with this powerful programming language.

1. Download and Install Golang

To start Golang, you need to download and install it first. You can download the latest version of Golang from the official website (https://golang.org/dl/). Note that Golang supports multiple operating systems, so make sure to download binaries that are compatible with your operating system.

Installing Golang is very simple. Just double-click the downloaded installation file and follow the wizard to complete the installation. After the installation is complete, you need to add Golang’s binary file path to the system’s environment variables. This way you can start Golang anywhere.

2. Verify that Golang is installed correctly

Before starting Golang, you need to confirm that it is installed correctly. To do this, open a terminal (or command prompt) and enter the following command:

$ go version

If you see the installed Golang version output, you have installed Golang correctly.

3. Learn Golang

After starting Golang, you need to learn Golang's syntax and features so that you can use it to write code. Golang has a simple syntax and a powerful concurrency model, which makes it possible to write efficient and scalable code using it.

You can learn Golang using online resources, books, documents, etc. Golang's official website (https://golang.org/) provides very good documentation and tutorials.

4. Build a development environment

While learning Golang, you need to prepare a development environment so that you can write, run and test code. You can use any text editor or integrated development environment (IDE) you like.

If you want to use a text editor, it is recommended that you use an editor with syntax highlighting and auto-completion features, such as Sublime Text, Atom, or Visual Studio Code. If you want to use an IDE, you can use Goland, VSCode or LiteIDE, etc.

5. Writing your first program

Now that you are ready to start Golang and learn its basics, here is how to write and run your first Golang Procedure Steps:

1. Open your text editor (or IDE) and create a new source file (file extension .go).
2. Enter the following code in the source file:

package main

import "fmt"

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

This is a classic "Hello, World!" program, which will output "Hello, World!" to the console.

3. Save the source file on your computer and navigate to the directory where the file is located on the command line.
4. Enter the following command at the command line:

$ go run <filename>.go

This will run your Golang program and output "Hello, World!" to the console.

6. Recommended resources

There are many excellent resources for learning and using Golang. The following are some recommended resources:

• Golang official website: https://golang.org/
• Go by Example: https://gobyexample.com/
• Go Web Examples: https://gowebexamples.com/

Summary

Starting Golang is a simple but important task, which lays the foundation for you to further learn and use Golang. By downloading and installing Golang, verifying that it is installed correctly, learning Golang syntax and features, setting up a development environment, and writing your first program, you can quickly start using Golang and use it to write high-quality and efficient code.
