Hello World!

If you're a programmer, you're probably very familiar with the famous "Hello World" program. This simple program, which typically prints the words "Hello World" to the screen, is often used as the first program that beginners write when learning a new programming language.

It also happens to be the post I always make every time I move from one blog to another. Today, I moved from back over to my website. It took some doing, but here we are, time for what may be the 10th migratory "hello world!"

But where did "Hello World" come from, and why is it so popular? In this blog post, we'll explore the history of "Hello World" and provide some examples of how to write a "Hello World" program in different programming languages.

The origins of "Hello World"

The "Hello World" program has its roots in the early days of computer programming. In the 1970s, a team of researchers at Bell Labs were working on a new programming language called C. One of the researchers, Brian Kernighan, wrote a short program to test the C compiler, and this program printed the words "hello, world" to the screen.


The program was so simple and elegant that it quickly became a popular example of how to use the C programming language. Over time, the program was adapted and used as a standard example in many other programming languages, and it became known as the "Hello World" program.

Today, "Hello World" is used in nearly every programming language as a simple way to test a basic program and get started with programming.

Writing a "Hello World" program

So, how do you write a "Hello World" program? It's actually very simple, and the code varies depending on the programming language you're using. Here are a few examples:

# "Hello World" in Python
print("Hello World")
// "Hello World" in JavaScript
console.log("Hello World");
// "Hello World" in Java
class HelloWorld {
  public static void main(String[] args) {
    System.out.println("Hello World");

As you can see, the basic structure of the "Hello World" program is the same in each language, but the specific syntax and code may vary.

In conclusion, "Hello World" is a simple program that has been used by programmers for decades as a way to test a basic program and get started with a new programming language. Whether you're just starting to learn to code or you're an experienced programmer, "Hello World" is a great place to start!
