Whether you’re a student, hobbyist, or aspiring professional developer, learning Golang can be a great addition to your skill set. So, let’s dive in and get started with Golang!

What is Golang

An open-source, compiled programming language developed by Google engineers is called Golang, popularly known as Go. It is intended to be effective, simple to use, and scalable for big systems. Golang is a fantastic language for both inexperienced and seasoned developers due to its clear syntax and strong standard library. Also, saying “Golang” is just fun!

History of Golang

Golang’s story begins in 2007 when three Google engineers (Robert, Rob, and Ken) were frustrated with existing languages and decided to create their own. They wanted a language that was fun to use and could handle the demands of Google’s massive systems. Thus, Golang was born! In 2009, Golang was released to the public and quickly gained popularity thanks to its simplicity and efficiency.

Installing Golang

Ready to get started with Golang? First things first, you’ll need to install it! Head over to the official Golang website and download the installation file for your operating system. Here’s some example code for installing on Linux:

sudo apt-get update
sudo apt-get install golang-go

For macOS, you can use Homebrew:

brew update
brew install go

Once the installation is complete, you’ll need to set up your environment variables. For Linux and macOS users, you can add the following line to your .bashrc or .bash_profile file:

export PATH=$PATH:/usr/local/go/bin

And that’s it! You’re now ready to start writing and running Golang programs.

Basic syntax and concepts

Golang is a statically-typed language with a simple syntax that makes it easy to read and write.

Here’s an example of a Golang function that prints “Hello, World!” to the console:

func main() {
    fmt.Println("Hello, World!")

Functions in Golang are defined with the func keyword and variables with the var keyword. In Golang, primitive data types include integers, floating-point numbers, booleans, and strings. If/else statements and for loops are control flow structures in Golang. Switch statements in Golang can be used for multi-way branching. In Golang, errors are handled as values that can be returned from a function. As a result, error handling in Golang is as simple and clean as the code itself.
