<"Hello World!">

Something that every YouTuber writes on code when teaching HTML to viewers. Literally everyone. It can also be seen in JavaScript and Unity.

Brackeys: *writes* <"Hello World!">; so this is how you write code in Unity

everyone: why does everyone with a tutorial write hello world?
Brackeys:*on next episode writes* <"Bye B****!">
everyone: much better

hello world

Computer Programming: The first program that a programmer writes in a language he is learning. Typically, the program simply opens a window that says "Hello World." The simplicity of the program makes it ideal for use as a comparison between different programming languages.

As a first step in learning Perl, create a "Hello World" application.

print("Hello World!")

You were really bored so you tried to learn how to code.

Joe: I am bored.
Joe clicks a YouTube video about coding.
Joe tries out the code that the guy on YouTube said to try out and types "print("Hello World!")".

hello world

Relating to the limited abilities of a person claiming to be knowledgable of computer science.
