Go is a fast, simple, and reliable programming language
Go is a compiled, statically typed language that has a syntax similar to C. It has a few keywords and features that make it easy to read and write. For example, it has garbage collection, which means you don't have to worry about memory management. It also has built-in support for concurrency, which means you can run multiple tasks at the same time using goroutines and channels. Go also has a rich standard library that provides many useful packages for common tasks such as networking, cryptography, testing, and more.

Verify that Go is installed correctly by checking the version
To make sure that Go is installed correctly on your system, you can check the version of Go using the command prompt. To open the command prompt, press Windows + R keys on your keyboard and type cmd in the Run box. Then press Enter or click OK. In the command prompt window, type go version and press Enter. You should see something like this:
C:\Users\user>go version go version go1.17.3 windows/amd64
This means that Go is installed correctly and you can see the version number and the architecture of your system.
How to set up your environment for Go development
Add Go bin directory to your PATH environment variable
To be able to run Go commands from any directory in your system, you need to add the Go bin directory to your PATH environment variable. The Go bin directory is where the Go tools and executables are stored. By default, it is C:\Go\bin, but it may be different if you changed the destination folder during installation. To add it to your PATH, follow these steps:
Open the Control Panel by clicking on the Start menu and typing Control Panel.
Click on System and Security and then click on System.
Click on Advanced system settings on the left side panel.
Click on Environment Variables at the bottom of the System Properties window.
In the User variables section, find the variable named PATH and click on Edit.
In the Edit environment variable window, click on New and type or paste the path of your Go bin directory.
Click on OK to save the changes and close all windows.
Create a workspace directory for your Go projects
A workspace directory is where you store all your Go projects and files. It is recommended to have a single workspace directory for all your Go development. By convention, it is named go and located in your home directory (C:\Users\user\go), but you can change it if you want. To create it, follow these steps:
Open File Explorer by clicking on the Start menu and typing File Explorer.
Navigate to your home directory (C:\Users\user) and right-click on an empty space.
Select New Select New and then select Folder.
Type go as the name of the folder and press Enter.
Set the GOPATH environment variable to your workspace directory
The GOPATH environment variable is used by Go to locate your workspace directory and its subdirectories. It is also used by some Go tools and packages to find and install dependencies. By default, it is set to your workspace directory (C:\Users\user\go), but you can change it if you want. To set it, follow these steps:
Open the Control Panel by clicking on the Start menu and typing Control Panel.
Click on System and Security and then click on System.
Click on Advanced system settings on the left side panel.
Click on Environment Variables at the bottom of the System Properties window.
In the User variables section, click on New.
In the New User Variable window, type GOPATH as the variable name and type or paste the path of your workspace directory as the variable value.
Click on OK to save the changes and close all windows.
How to write and run your first Go program
Create a file named hello.go in your workspace directory
To write your first Go program, you need to create a file with the .go extension in your workspace directory. You can use any text editor or IDE of your choice, but for this example, we will use Notepad. To create the file, follow these steps:
Open Notepad by clicking on the Start menu and typing Notepad.
In Notepad, click on File and then click on Save As.
In the Save As window, navigate to your workspace directory (C:\Users\user\go) and type hello.go as the file name.
Click on Save to create the file.
Write a simple program that prints "Hello, world!"
To write a simple Go program, you need to follow some basic rules and conventions. A Go program consists of one or more packages, which are collections of related code. Each package has a name and a path. The main package is the entry point of the program and must have a main function. The main function is where the program starts executing. To print something to the standard output, you can use the fmt package, which provides formatted input and output functions. To import a package, you use the import keyword followed by the package path in double quotes. To write a simple program that prints "Hello, world!", type or paste the following code in your hello.go file:
package main import "fmt" func main() fmt.Println("Hello, world!")
Run the program using the go run command
To run your Go program, you can use the go run command, which compiles and executes your code without producing an executable file. To run your hello.go program, follow these steps:
Open the command prompt by pressing Windows + R keys on your keyboard and typing cmd in the Run box. Then press Enter or click OK.
In the command prompt window, navigate to your workspace directory (C:\Users\user\go) by typing cd go and pressing Enter.
Type go run hello.go and press Enter. You should see something like this:
C:\Users\user\go>go run hello.go Hello, world!
Congratulations! You have just written and run your first Go program!
