Usually hello world is used to peek at a language's syntax but it can also explain to beginners the concept of semantics.
This is the beginning of this passle and here's the general semantics of what's to come.
I'll try to leave a few technical gems here when I can but to add something a little different, there'll be some rpg plots, write ups and articles that peak my interest.
A "Hello world" program is a computer program that outputs "Hello, world" on a display device. Because it is typically one of the simplest programs possible in most programming languages, it is by tradition often used to illustrate to beginners the most basic syntax of a programming language.
