Go is a modern programming language that is widely popular for its efficient features, and many developers choose to use Go to build web applications and other high-performance applications.
In this article, we will explain how to install and set up Go on your computer. We'll walk you through the process from downloading and installing to creating a "Hello World" application.
Step 1: Download Go
To install Go, you need to download the Go binary installation package. The latest version of Go can be found from the official website https://golang.org/dl/. Once downloaded you can choose to move it to an easily accessible location, such as your home directory.
Step 2: Install Go
The process of installing Go is simple, just open your terminal and enter the following command:
$ tar -C /usr/local -xzf go$VERSION.$OS-$ARCH.tar.gz
This will install Go to /usr/local/go directory, where $VERSION is the version you downloaded, such as 1.16, $OS represents your operating system (such as linux, darwin, windows, etc.), and $ARCH represents your architecture (such as amd64).
Step 3: Set Go environment variables
If you want to use Go anywhere, you need to set Go environment variables. Go environment variables can be added to your system files using the following command:
export PATH=$PATH:/usr/local/go/bin
Step Four: Verify Installation
Once the installation is complete, you can verify your Go installation by entering the following command :
$ go version
If everything is fine, the output will show the installed Go version.
Step Five: Create your first "Hello World" application
Now that you have Go installed and environment variables set, you can start creating your own Go application. We will create a simple "Hello World" program to illustrate how to program in Go.
First, create a file named hello.go, and then enter the following code:
package main import "fmt" func main() { fmt.Println("Hello, world!") }
The above code uses the fmt package to print "Hello, world!" to the console. Next, open your terminal and build the binary for this application using the following command:
$ go build hello.go
This will create a binary executable named hello which you can run using the following command:
$ ./hello
The output should be "Hello, world!", which means your first Go application has been successfully created.
Conclusion:
Congratulations! Now you know how to install and set up Go on your computer. It also shows how to write a simple "Hello World" application in Go. Go is a fast and full-featured programming language that you can use in different areas such as web applications, APIs, gadgets, etc. Hopefully this article will help you get started learning and using the language.

Go language error handling becomes more flexible and readable through errors.Is and errors.As functions. 1.errors.Is is used to check whether the error is the same as the specified error and is suitable for the processing of the error chain. 2.errors.As can not only check the error type, but also convert the error to a specific type, which is convenient for extracting error information. Using these functions can simplify error handling logic, but pay attention to the correct delivery of error chains and avoid excessive dependence to prevent code complexity.

Use the recover() function in Go to recover from panic. The specific methods are: 1) Use recover() to capture panic in the defer function to avoid program crashes; 2) Record detailed error information for debugging; 3) Decide whether to resume program execution based on the specific situation; 4) Use with caution to avoid affecting performance.
