Hello, World!

Experience Level: Beginner

If you choose to use WordPress as your blog platform (like we did), you will se that the first blogpost is by default named “Hello wordl!”. Does this title have a meaning or is it just randomly created by WordPress? I can tell you that it is not random. The phrase “Hello, World!” is one of many naming conventions in the field of programming. The phrase is used by programmers to test their code and display something. It is just a tradition in to use “Hello, World!” for this purpose. If you buy a beginner’s book about programming (doesn’t matter which programming language) the first program example will often be a “Hello, World!” program. It simply demonstrates the syntax of the particular language and prints out the phrase on the screen.

The usage of “Hello, World!” was popularized by the book: The C Programming Language by Brian Kernighan and Dennis Ritchie, published in 1978. But the phrase can be traced even further back. Kernighan used it already in 1972 when he wrote a tutorial to the language B.

Let’s stick to the tradition and name the first blog post “Hello, World!”
