Lua by Example: Multiple Results

Lua has built-in support for multiple results.
This function returns two number results	local function values() return 3, 7 end
Here we use the 2 different return values from the call with multiple assignment.	a, b = values() print(a) print(b)
If you only want a subset of the returned values, use the blank identifier `_`.	_, c = values() print(c)
The Multiple Results page in the Programming in Lua book has more examples that cover the many edge cases

	$ lua multiple-results.lua 3 7 7
Accepting a variable number of arguments is another nice feature of Lua functions; we’ll look at this next.
