For what is "debug.traceback()"?

I read the documentation, but I didn’t understand it very well, so I need someone to explain it to me more easily…

it’s used to trace back a function call and figure out where it came from. its use case is pretty rare; you’d mainly use it when you have modules calling other modules’ deeply nested functions. it outputs the same thing as roblox output when you get an error.
for simplicity here’s an example

local function a()
	print(debug.traceback())
end

local function b()
	a()
end

b()

if you execute this in a Script inside ServerScriptService you’ll get this in your output

ServerScriptService.Script:2 function a
ServerScriptService.Script:6 function b
ServerScriptService.Script:9

so basically it outputs the path from which the function was called

It allows you to figure out from where a specific line of code is being run, as shown in @TopBagon’s example, like the blue text that appears when something errors that allows you to easily “trace back” how something was run.
