<"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
