<title>Var Args</title> <cat>Dev.Lua</cat> 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 **{ ... }**.⤶ ⤶ Varargs are variable number of arguments, meaning the amount of arguments is undefined.
