This will install Golang Installed in the /usr/local/go directory.

Configuring system environment variables

In order to facilitate the use of Golang, you need to add the following content to the .bashrc file:

export PATH=$PATH:/usr/local/go/bin

Enable environment variables Take effect

Enter the following command to make the environment variable take effect:

source ~/.bashrc

go version

If Golang was successfully installed, results similar to the following will be displayed:

go version go1.x.x linux/amd64

Using Golang

Editor's Choice

Like other programming languages, writing code in Golang requires choosing a good editor. Golang officially provides an official integrated development environment (IDE) that can be used to edit Golang code, the most famous of which is GoLand. In addition, there are many other text editors and IDEs available for Golang development, such as Visual Studio Code, Sublime Text, etc.

Writing the first Golang program

Open the editor and enter the following code:

package main

import "fmt"

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

Save the code and name the file "helloworld.go ". Use the terminal to enter the directory where the file is located and enter the following command:

go run helloworld.go

After successful execution, "Hello World!" will be output on the screen.

In short, Golang is a programming language that is easy to learn and efficient to develop. Whether it is developing web applications, mobile applications, games, etc., Golang is increasingly favored by developers.
