Go is an open-source programming language supported by Google
Go is free to use and modify, and it has a large and active community of developers who contribute to its development and improvement. You can find the source code, documentation, tutorials, and other resources on go.dev, the official website for Go. You can also access the Go module mirror and checksum database run by Google, which provide fast and secure downloads of modules from third-party sources.
Go is easy to learn and great for teams
Go has a simple and consistent syntax that makes it easy to read and write. It has only 25 keywords and a few basic data types, such as numbers, strings, booleans, arrays, slices, maps, and structs. It also supports common programming features such as functions, methods, interfaces, pointers, and error handling. Go has a built-in tool called gofmt that automatically formats your code according to a standard style guide, which helps to maintain code quality and consistency across teams.

Go has built-in concurrency and a robust standard library
Go supports concurrency, which means that it can run multiple tasks at the same time without blocking or waiting for each other. This makes it ideal for developing applications that need to handle high volumes of requests or data in parallel. Go uses a concept called goroutines, which are lightweight threads that can communicate with each other through channels. Go also has a rich and comprehensive standard library that provides packages for common tasks such as input/output, networking, cryptography, testing, debugging, and more.
Go has a large ecosystem of partners, communities, and tools
Go is used by many organizations in various industries, such as Google, Uber, Netflix, Dropbox, Docker, Kubernetes, and more. You can find many examples of how they use Go to power their software and services on go.dev/solutions. You can also join the global community of Go developers who share their knowledge and experience through blogs, podcasts, newsletters, forums, meetups, conferences, and more. You can find many resources to help you learn and improve your skills on go.dev/learn. Additionally, you can use many tools and frameworks that are compatible with Go, such as editors, IDEs, debuggers, testing tools, web frameworks, databases, etc.</ How to download and install Go on your computer
If you want to start programming in Go, you need to download and install the Go tools on your computer. Here are the steps to do that:
Download the official binary distributions from go.dev/dl
Go to [go.dev/dl](^1^) and click on the download button for your operating system. You will get a file with a .msi extension for Windows, a .pkg extension for Mac, or a .tar.gz extension for Linux. Save the file to your preferred location.
Follow the installation instructions for your operating system
Depending on your operating system, you will need to follow different installation instructions. For Windows, you need to open the .msi file and follow the prompts to install Go. By default, the installer will install Go to Program Files or Program Files (x86). You can change the location as needed. For Mac, you need to open the .pkg file and follow the prompts to install Go. By default, the installer will install Go to /usr/local/go. You can change the location as needed. For Linux, you need to extract the .tar.gz file into /usr/local, creating a Go tree in /usr/local/go. You can use the following command to do that: $ rm -rf /usr/local/go && tar -C /usr/local -xzf go1.20.4.linux-amd64.tar.gz
Verify that you've installed Go by typing go version in a command prompt
To check that you've installed Go correctly, you need to open a command prompt and type the following command: $ go version This command should print the installed version of Go. If you see an error message or no output, it means that something went wrong with the installation. You may need to check your environment variables or reinstall Go.
How to write and run your first Go program
Now that you have Go installed on your computer, you can write and run your first Go program. Here are the steps to do that:
Create a file named hello.go with a simple Hello World program
In your text editor, create a file named hello.go in which to write your code. Paste the following code into your hello.go file and save the file.
package main import "fmt" func main() fmt.Println("Hello, World!")
This is your Go code. In this code, you:
Declare a main package (a package is a way to group functions, and it's made up of all the files in the same directory).
Import the popular fmt package, which contains functions for formatting text, including printing to the console. This package is one of the standard library packages you got when you installed Go.
Implement a main function to print a message to the console. The main function is the entry point of any executable program in Go.
Use the go run command to compile and execute your program
To run your program, you need to use the go run command, which compiles and executes your code in one step. Open a command prompt and navigate to the location of your hello.go file. Then type the following command: $ go run hello.go This command should print Hello, World! in the command prompt.
Use the go build command to create an executable file from your program
If you want to create an executable file from your program, you can use the go build command, which compiles your code and produces a binary file that you can run without using go run. To do that, type the following command: $ go build hello.go This command will create a file named hello.exe on Windows, hello on Mac, or hello on Linux. You can run this file by typing its name in the command prompt: $ ./hello This command should also print Hello, World! in the command prompt.
