vararg#512403
Varargs are variable number of arguments, meaning the amount of arguments is undefined.⤶
The most notable function to take varargs is <page>Global.print</page>. ⤶
⤶
To create a function with varargs, you must set the **last** parameter of the function to **...** (that's three periods). You may use a combination of normal arguments with varargs, but the varargs **must** appear as the last parameter. Inside of the function's body, you may access each argument by creating a table of the varargs with **{ ... }**⤶
⤶
In the table, each key is the respective number of the argument, with the value being the value passed.⤶
⤶
Varargs are stored at negative indices, so functions such as <page>debug.getlocal</page> may access the values where -1 is the first vararg passed, -2 is the second, etc. ⤶
⤶
You may create varargs yourself with <page>Global.unpack</page>.⤶
<example>⤶
<description>Finds the average of a set of numbers.</description>⤶
<code>⤶
function average(...)⤶
local args = {...} ⤶
local result = 0⤶
⤶
for k, v in pairs(args) do⤶
result = result + v⤶
end⤶
⤶
return result / #args⤶
end⤶
⤶
print(average(5, 15, 30, 7, 52))⤶
