In particular, the call string.sub(s,1,j) returns a prefix of s with length j, and string.sub(s, -i) returns a suffix of s with length i.
(string) = string.sub(s,i,j)
Parameters
s: (string) string to get substring from
i: (number) start index of substring
j: (number) index of the last character of substring optional

Returns (string) substring
