"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.

"Hello, World!"

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

///, 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.

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).
