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.

RoadLang, 59 bytes

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.

"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.

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).

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.
