The phrase “Hello, world!” first appeared in the book The C Programming Language by Brian Kernighan and Dennis Ritchie. It has become traditional for the first program written by beginners in any programming language.
This simple line helps to check whether the development environment is set up correctly and whether the code works correctly.In addition to programming, the expression “Hello, world!” is used in a broader context, for example, when someone starts a new project, enters a new market, or tries something for the first time. It’s a universal symbol of beginning, combining the enthusiasm of discovery with the simplicity of the first step.
