Go language supports multiple operating systems including FreeBSD, Linux, Solaris and Windows. Go language is a cross-platform and cross-operating system language. Due to its modular design and modularity, i.e. the code is compiled and converted into the smallest possible binary form, the Go language requires no dependencies; its code can be compiled on any platform (multiple operating systems) and Compile on any server and application.
The operating environment of this tutorial: Windows 7 system, GO version 1.18, Dell G3 computer.
Go (The Google Programming Language) language is the second open source programming language released by Google in 2009. The Go language is specially optimized for programming multi-processor systemsapplications. Programs compiled using Go can be comparable to the speed of C or C code , and is more secure and supports parallel processes. Go supports object-oriented and has real closure and reflection functions.
Go was developed by Robert Griesemer, Rob Pike, Ken Thompson since the end of 2007, and later joined by Ian Lance Taylor, Russ Cox and others, and was finally open sourced in November 2009 , released Go 1 stable version in early 2012. The development of Go is now completely open and has an active community.
Hardware architecture
Go language design supports mainstream 32-bit and 64-bit x86 platforms. It also supports 32-bit ARM architecture.Operating System
Go language can support a variety of operating systems including FreeBSD, Linux, Solaris and Windows.Go language is a cross-platform and cross-operating system language.
Go language, like Java language, supports platform independence. Due to its modular design and modularity, i.e. the code is compiled and converted into the smallest possible binary form, therefore, it requires no dependencies. Its code compiles on any platform and on any server and application. No need to use a virtual machine, the Go language code can be directly output as a binary executable file. Moreover, the Go language has its own linker and does not rely on the compiler and linker provided by any system. Therefore, the compiled binary executable file can run in almost any system environment.

Sublime Text 3 (hereinafter referred to as Sublime) GoSublime gocode MarGo combination.
Its advantages include:
Automated prompt code.
Automatically format the code when saving, making the code you write more beautiful and in line with Go standards.

Vim It is a text editor developed from vi and enjoys the title of "God of Editors". It is particularly rich in functions that facilitate programming, such as code completion, compilation, and error jumping, and is widely used among programmers.
Emacs is a text editor developed by the GNU open source organization. It is also an integrated environment. It was once jokingly called "an operating system disguised as an editor."
Eclipse is also a very commonly used development tool. You can use Eclipse to write Go programs.
Goland is an integrated development environment specifically for the Go language. It has now become a paid software.
Next we will write the first Go program hello.go (The extension of the Go language source file is .go) , the code is as follows:
hello.go file
package main
import "fmt"
func main() {
fmt.Println("Hello, World!")
}
To execute Go language code, you can use the go run command.
Execute the above code output:
$ go run hello.go Hello, World!
In addition, we can also use the go build command to generate binary files:
$ go build hello.go $ ls hello hello.go $ ./hello Hello, World!
