We've all been here before. When we start learning a language, the first thing we probably get taught to do is to output Hello, world! to the console. For some, "Hello, world!" can turn into a new opportunity, a new career, a new life..
But where did it originate?
The origins of hello world are unclear, but the phrase was first seen in Brian Kernigham’s book in 1972, A Tutorial Introduction to the Language B. After that, it was used in The C Programming Language in 1978, which is what really made the phrase popular.
What it looks like in different languages today
Here is what "Hello, world!" looks like in some of the most popular programming languages today:
