Are you bored of writing “Hello, World!” in the same programming language over and over again?😴 Do you want to spice up your coding skills and learn new languages in a fun and easy way?🌶️ Well, you’re in luck because today we are going to explore how to write “Hello, World!” in 20 different programming languages.🌎
As developers, we know that learning the basics is the key to mastering any new programming language. “Hello, World!” is a simple program that is often used as the first step for learning a new language. It’s a way to test that your development environment is set up correctly and that you understand the basic syntax and structure of the language.
But what exactly is “Hello, World!” and why is it so popular?
The History of Hello, World!
The origin of “Hello, World!” can be traced back to the 1970s when it was used in a tutorial for the C programming language by Brian Kernighan and Dennis Ritchie. They wrote:
The only way to learn a new programming language is by writing programs in it. The first program to write is the same for all languages: Print the words hello, world This is the basic hurdle; to leap over it you have to be able to create the program text somewhere, compile it successfully, load it, run it, and find out where your output went. With these mechanical details mastered, everything else is comparatively easy.
Since then, it has become a tradition in the programming community to write a “Hello, World!” program in any new language you learn. It’s a simple way to get started and familiarize yourself with the basics of the language.
So, let’s get started and see how to write “Hello, World!” in various programming languages.
