Raku, 19 bytes

"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.

///, 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.

"Hello, World!"

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

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).
