'Hello world' is there any reason behind why programming languages uses that 2 words?

Answer 1

As in so much else: historical reasons... someone got started with it, others copied it. The first recorded occurrence of a “hello, world” program can be found in “A TUTORIAL INTRODUCTION TO THE LANGUAGE B” written in 1972 (chapter 7)

Answer 2

Don’t get it twisted though, it could just aswell be “Yo, 2Pac”

Answer 3

Well "hello world" actually means that you know the basics of the programming language/script you are using to the world.

Answer 4

I guess for the same reasons that errors are called bugs. Someone used it once because their mechanical computer physically had a bug (dead moth) in it and it caught on so now everyone uses it.
