"@" Symbol seems to be a valid keyword / operator?

[noober2359 (Marcos)]

So i was scripting and accidentally typed in the @ symbol, and it turned red, like local or function keywords, however i got an error from script editor, it says:

Attribute name is missing

Then i typed in the command bar something like

print(@hi)

And this is the error i got:

print(@hi):1: Invalid attribute '@hi'

Then i started looking on the internet to find out what this meant or how to use it but i didnt really find any information about it, since it seems to be a Luau feature only
Does anyone know what this is?

The “@” symbol represents attributes in lua which just determine how a script runs.

Also try googling first! Here is a topic I solved previously though:

What does this "@" mean
