What is Go and why should you learn it?




Go is an open source programming language that makes it easy to build simple, reliable, and efficient software. It was created by Google in 2009 and has since gained popularity among developers around the world.


Go has many features that make it attractive for developers, such as:


  • Concurrency: Go supports multiple threads of execution that can communicate through channels, making it possible to write scalable and concurrent programs.



  • Garbage collection: Go automatically manages memory allocation and deallocation, freeing developers from manual memory management.



  • Cross-platform support: Go can run on various operating systems and architectures, such as Windows, Linux, Mac OS X, ARM, and AMD64.



  • Rich standard library: Go provides a comprehensive set of packages that cover common tasks such as input/output, networking, cryptography, compression, testing, and more.



Go is widely used in various domains, such as web development, cloud computing, data science, and system programming. Some of the well-known projects that use Go are Docker, Kubernetes, TensorFlow, and Hugo.


How to download and install Go on your computer?




You can download the official binary distributions of Go from the Go website or install Go from source if a binary distribution is not available for your operating system and architecture.

Downloading and installing Go from the Go website




To download and install Go from the Go website, follow these steps:


  • Visit the Go website and choose the binary distribution that matches your operating system and architecture.



  • Download the file and follow the installation instructions for your operating system. You may need to extract the file, move it to a specific location, or set some environment variables.



  • Verify that Go is installed correctly by opening a terminal or command prompt and typing go version. You should see the version of Go that you installed.



Installing Go from source




To install Go from source, you need to have a C compiler and Git installed on your computer. Then, follow these steps:


  • Clone the Go repository from GitHub by typing git clone https://github.com/golang/go.git in your terminal or command prompt.



  • Change your working directory to the Go repository by typing cd go.



  • Checkout the latest stable release of Go by typing git checkout go1.17.1, where go1.17.1 is the current version of Go as of this writing. You can check the available releases by typing git tag.



  • Run the all.bash script by typing ./all.bash. This will build Go and run all the tests. This may take some time depending on your computer's speed and resources.



  • If the script finishes successfully, you should see a message like ALL TESTS PASSED. This means that Go is installed correctly.



  • Add the bin directory of the Go repository to your PATH environment variable so that you can run Go commands from anywhere. You can also set the GOROOT environment variable to point to the Go repository if you want.



  • Verify that Go is installed correctly by typing go version. You should see the version of Go that you built from source.



How to write and run your first Go program?




You can use any text editor or IDE to write Go code, but you need to follow some conventions, such as using the .go file extension, organizing your code into packages, and formatting your code with gofmt or goimports.


You can use the go command to compile and run your Go code, as well as to manage your dependencies, test your code, and generate documentation.


Writing a simple "Hello, world!" program in Go




To write a simple "Hello, world!" program in Go, create a file named hello.go in your preferred directory and type the following code:


```go package main import "fmt" func main() fmt.Println("Hello, world!") ``` This code defines a package named main, which is the default package for executable programs in Go. It also imports the package, which provides formatted input/output functions. Then, it defines a function named main, which is the entry point of the program. Inside the function, it calls the fmt.Println function to print "Hello, world!" to the standard output.


Running your Go program with the go command




To run your Go program with the go command, open a terminal or command prompt and change your working directory to where you saved your hello.go file. Then, type go run hello.go. This will compile and execute your program in one step. You should see "Hello, world!" printed on your screen.


You can also compile your program into an executable file by typing go build hello.go. This will create a file named hello (or hello.exe on Windows) that you can run from anywhere by typing ./hello.
