Go, or we can call it Golang, an open-source programming language created by Google in 2007 and publicly announced in November 2009. This procedural language allows users to build dependable, reliable, and efficient applications. Many well-known organizations prefer to Go programming languages such as Mangodb, Soundcloud, Netflix, Uber, etc.
Multiple advantages can be listed to show why Go should be preferred to be used.

Once your directory is created, make a new file named “hello.go” and write a program to print “Hello World” in the terminal:
To get the output of this program, type:
Another aspect of Golang is that you can also build executable files from source code.
To run the hello.go file, use:
Now, run that executable file:
Conclusion:
In this guide, we have installed Go on Ubuntu and also checked its example as well. Go is a procedural language developed by Google, and many applications like Terraform, Docker, are using this language.
