"Hello, World!"

No, I'm not joking. This ridiculous language for a code golf actually beats some of the more normal languages.

That's it.

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

wagwan my slime
man say"Hello, World!"
chat wit u later fam

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.

///, 13 bytes

Hello, World!

Someone had to.

18 bytes using replacement

/x/H/xello, World!

23 bytes using two-layer replacement

/a/Hello, World!//b/a/b

a is replaced with Hello, World! in /b/a/b, creating /b/Hello, World!/b which prints Hello, World! at the end.

Z80 Assembler, 50 bytes

org 256
ld de,m
ld c,9
jp 5
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.

C (gcc), 30 bytes

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.
