--So this is Lua's commenting stuff. I think that GLua, what Garry Newman uses for Garry's Mod allows // as a prefix.

function AddNumbers(number1, number2) --Simple, clean. I think you're allowed to specify returns, but it defaults to auto.

io.write("String concatination is".." so fucking easy.".." You can even do it with numbers: "..500);

local num = number1 + number2; --You don't need to specify any types ever.
return num, num + 1; --Multiple return types; compacts it into an array before returning.

end --This is like pseudocode. Fucking love it.

--[[ Comment block syntax looks rad. ]]--

for i = 0, 10 do --Don't need to define a second value type or name, just loops to the second number.
    io.write("Ay lmao"..i);
end

--Now.. My favourite. The 'Do while' loop.
repeatVal = 0;
repeat
    io.write("Repeating...");
until repeatVal > 10;

-- Repeat until. So sleek.
