Why do so many instructors/tutorials/books leave the comma out of “Hello, world?” It bugs the shit out of me. I know they know better...

I have quite literally only seen a comma in a single hello world program from some random Indian guy with terrible English.

It's not wrong without a comma at all.

Hello Broseph,
As you can see when I write a Hello xxx there is no comma between. Having a comma between them feels like a general greeting (hello) and then a special greet for the the thing after the comma, basically like "Hello everyone, Broseph"

To be fair the question mark bothers me more than the comma there :P

@fuckwit The punctuation mark goes inside the quotes. It’s not my fault English is stooopid 🤣

@filthyranter I’ve never heard of a “Hello world.”

@broseph It's a greeting to the world.
Clarifying in verbosity:

Hello world! ->
I am announcing my existence to the world!

@filthyranter you’re addressing the world. Ya neeeeed a comma, man...

You really need to read your sentences carefully if you are going to nit-pick about grammar and punctuation.

JesusFuckingChrist. I was venting, but this isn’t a hill I’m willing to die on.
