nilWhy is i3 nil instead of 1?
with a few exceptions, Lua ignores spaces and newline characters. The original code can be represented as
local i3 = 1, and the print (i3)
assignment statement evaluates all its expressions before performing the assignment. So print before the assignment, but in the end i3 is assigned to 1.
local i3 = 1,
print (i3)-- nil
print (i3)-- 1
