Hello World

Definitions

1. The conventional first program used to demonstrate a language, toolchain, or runtime by printing a simple greeting. It became a universal computing ritual because it proves the environment works with the smallest possible visible result.

   In plain English: The simplest first program people write to prove a coding setup works.

   Example: "If your compiler setup can’t run hello world yet, don’t touch the build system."
