"Hello, World!".say
Explanation
First second answer of the.. entire site, actually. Nothing special. I don't think this can go shorter, but this is Raku, who actually knows. I made this post to (possibly) try and set a precedent for what a answer should look like. Obv you don't have to explain it, but it's nice.

man say"Hello, World!"

My first RoadLang answer! And probably the first one on this site!
Removing any of the words says "Aight the lad's lost the plot", so I think this is the most minimal answer I can get here.
Thanks to Quintec for patching string parsing so that this works.

m:db"Hello, world!\r$"
With assembler there's usually the problem which machine or operating system the program is for. I've chosen CP/M here as it runs on a variety of different machines with a Z80 processor.
CP/M programs start at address 0x100, but the decimal representation 256 is shorter.
The program loads the address of the $-terminated string into the D & E register pair, then the number of the print text subroutine (9) into the C register, and jumps to the BDOS entry. It uses the RETurn of that routine to end itself, instead of CALLing the BDOS and needing an own RET instruction in the program.

That's it.
An empty program in Stuck prints "Hello, World!". It's literally hardcoded in the interpreter.

Or if you prefer to beat around the bush...76 bytes.

Basically just keeps replacing the current cell value with the ASCII value of whatever character in "Hello, World!" its printing and moving on. I might add a more detailed explanation later (or maybe someone else can, if they feel like it).

main(){puts("Hello, World!");}
This is using GNU C extensions. GNU C allows main() over int main(), ss well as using puts without including stdio.h.

printf(char*);main(){printf("Hello, World!");}
printf(char*);(14 bytes) is better than
#include <stdio.h>\n(19 bytes)
